The artillery were ordered to fire on chosen targets through the night, and patrolling was active.
A great deal of movement had been seen throughout the day of men and light railways. Troops were seen detraining at Vitry.
And that night there was an inter-battalion relief on the right, the Queen’s Westminsters relieving the 2nd London. The party sent to relieve Gavrelle Post found it occupied by two dead men only—the remainder of the garrison had entirely disappeared. Signs of a struggle were there, but no one on either flank had reported the post being attacked, and, apparently, nothing unusual had been seen.
Gen. Dudgeon ordered both brigades to do their utmost to secure a German prisoner. Every effort was made, but the enemy was found more than ever on the alert, with parties lying out to catch patrols. It is curious that one patrol reported the enemy repairing their wire—it is probable that they were cutting it down.
The attack was coming, and Divisional Headquarters strained every nerve to direct, encourage, and advise for the struggle. Some of the orders are not too easy to understand, and one is of interest as an example of rumour being accepted as fact.
The artillery, of course, was very busy, and we find an instruction to cut German wire and to keep the gaps open! And the order we refer to as being founded on rumour was as follows: “In view possible appearance enemy agents warn all ranks against use of word RETIRE. Any person using this word before or during an attack to be shot.” This was, no doubt, based on a much-circulated statement that the Fifth Army debacle was largely due to German agents, dressed as British officers, giving the order to retire. We cannot believe in a swarm of disguised Germans.
It must, however, have been a very weighty consideration which induced the Higher Command to order an extension of divisional front on the 27th. General Sir H. de Lisle, better known as the commander of the 29th Division and now in command of the XIII Corps, was ordered to take over the line to the Souchez River, on his left. This meant that the 56th Division had to relieve the 3rd Canadian Division, on the left, at Tommy and Arleux Posts during the night of 27th/28th March. At the same time the division was again ordered to treat the front line as an outpost line, and to fight on the line between Ditch Post and Willerval South. But at the last moment the front line was ordered to be held as such so as to conform with the 4th Division on the right; the 56th Division was already so stretched out that this curious eleventh-hour change did not make much difference.
The Vimy Ridge lay behind the division, but the ground they fought on was not level. The 4th Division, on the right, was on high ground, and Gavrelle lay in a slight depression; the ground rose again towards Bailleul East Post, and fell once more in the direction of Oppy. The division was, however, on a forward slope which gave them good observation from a somewhat exposed position (see map contours).
The rearrangement of the line, which took place during the night, gave the Queen’s Westminsters the right, holding Towy Post and Gavrelle Post with one company, while the other three companies held posts defending Naval Trench. The London Rifle Brigade held Mill, Bradford, and Bird Posts with two companies and one platoon, the remainder of the battalion holding posts on the Marine Trench line. The third battalion of the brigade, the 2nd London Regt., held the Ditch, Bailleul, and Bailleul East line. Behind them, in the Farbus line, was one company of the 5th Cheshire Regt., and in reserve the 169th Brigade held two companies of the 1st London Regt., attached from the 167th Brigade, and a detachment of the 176th Tunnelling Company, who were in the Point du Jour Post.
The 168th Brigade, on the left, held Beatty, Wood, and Oppy Posts with two companies of the 4th London Regt., and two in support on the line Duke Street; and Tommy and Arleux Posts with the Kensingtons, two companies in the front line and in support.
The actual distribution of troops on the left is not very clear, as the redistribution was not complete when, at 3 a.m. on the 28th March, the enemy opened a furious bombardment. We find a note that the London Rifle Brigade had not at that hour relieved Bailleul East Post, and that one company of the 1st Canadian Rifles were still holding Sugar Post. This latter company remained at Sugar Post throughout the battle, being placed, with that complete disregard of all, except the winning of the battle, which characterised the Canadians, under the orders of the 168th Brigade. But the London Scottish were also in this Sugar Post-Willerval line. In the Farbus line were two platoons of the 5th Cheshires, and behind them, in the Point du Jour-Ridge Post line, two companies of the 1st London Regt. and one and a half companies of the 5th Cheshires.
The two remaining battalions of the 167th Brigade and three field companies of Royal Engineers were in Divisional Reserve.
The opening of a modern battle is, with few exceptions, a matter of artillery. Brig.-Gen. Elkington’s diary gives us some interesting facts:
“On the morning of the 28th March the 56th Division was holding a line south of Gavrelle to Arleux, a front of about 5,000 yards. To cover this front the field-guns under the command of the division consisted of the 56th Divisional Artillery and 9 guns of the 52nd Army (Field Artillery Brigade), or 45 18-pounders and 12 4·5 howitzers. Six 6-inch Newton mortars were in action in the first-line system, and three were covering the Bailleul-Willerval line (that is our main line of resistance). Of the former, only two were manned, as all the ammunition at the other mortars had been expended previously, in accordance with orders which, later on, were cancelled, but not before the ammunition had been expended.
Between 3 a.m. and 3.20 a.m. the Germans put down a heavy barrage of gas and H.E. shells of all calibres on the Bailleul-Willerval line and the support line. At 4 a.m. the barrage increased over the whole of the front-line system and our posts were heavily bombarded with trench mortars. From 6 a.m. the hostile barrage of all calibres was heavily concentrated on the front line, and continued to be intense on this area until 7.15 a.m.
During the above periods, that is from 3 a.m. until 7.15 a.m., our artillery was firing heavily on the enemy’s front system of trenches, special concentrations being put down, in co-operation with the heavy artillery, on lines of organised shell-holes. It was considered at the time that these shell-holes were temporary trench-mortar emplacements, but from information given by prisoners after the attack, it appears likely that they were the assembly positions of the assaulting troops. From 6.45 a.m. onwards “counter preparation” was put into effect. At 7.15 a.m. the hostile barrage lifted from the front line to our support line, and the S.O.S. went up in the Gavrelle sector and was repeated almost immediately in the Oppy sector. Our S.O.S. was put down over the whole of the divisional front at the same time.”
As may be imagined, the effect of this bombardment was terrible. The bulk of the forward posts were obliterated. But even such concentration as the Germans directed against the front line was not sufficient to destroy all life—it could not deal with the whole of the line. Towy Post and Wood Post had, during the last few days, been subjected to a great deal of enemy attention, and the posts had been moved—but even so the casualties were severe. One survivor came out of Mill Post and reported that the trenches had been “blotted out,” and that the entrance to a big dug-out there was blown in and destroyed.
The Germans, advancing almost shoulder to shoulder, entered Gavrelle, which, as we know, was in a hollow. Although there was no living soul there to oppose them, the machine gunners had the place under indirect fire from fourteen guns, and the enemy losses were severe. But the first stages of the battle were centred round Towy and Wood Posts.
Capt. G. A. N. Lowndes, of the Queen’s Westminsters, was in command of Towy Post, and with the lifting of the enemy barrage and the appearance of the first Germans there came from the post the crackling sound of rifle fire, joined, almost at once, by the rattle sound of Lewis guns, until the whole developed into what might be described as a roar. But the enemy was in Gavrelle and the undefended portions of the front line on either side of Towy Post. Once in the trenches, the storming troops could work slowly forward under some sort of cover. To the rifle fire of the defenders was soon added the crash of bombs. The enemy was confident; he worked slowly and surely round the post.
The glorious little band of Queen’s Westminsters knew what was happening, but kept cool. Gradually they were forced into a small and cramped area; Lewis guns and rifles dealt with Germans in the open, clearing the ground round about and forcing the enemy to seek the safety of the battered trench; but the store of bombs was getting low.
Capt. Lowndes, ably supported by 2/Lieuts. L. W. Friend and J. C. B. Price, after hanging on to the last moment, directed his dwindling company to fight through the Germans in rear, using the remaining bombs, and swiftly, desperately, they broke through and reached Naval Trench and joined the rest of the battalion round headquarters.
But the Germans, coming through Mill Post, were already in Marine Trench, and Lieut.-Col. Glazier, commanding the Queen’s Westminsters, passed a portion of his force into Thames Alley to form a flank.
Now trouble came from the right. The Lancashire Fusiliers, of the 4th Division, fell back on to the Ditch Post line, and the enemy entered Humid Trench. Col. Glazier swung back his right flank into Towy Alley, and held the Germans firmly. And then for a moment the fortunes of war turned against the Queen’s Westminsters.
The 56th Divisional Artillery, aware that the enemy were in our lines, attempted to adjust their barrage in consultation with brigadiers. It was a most difficult task, for, needless to say, communication was almost non-existent. At the junction of Naval and Towy Trenches was a block, and in front of it the enemy was held, but the artillery, probably seeing the Germans in Humid and the end of Naval Trenches, put down their barrage too close and blew in our block. The German hordes quickly took advantage of this bit of luck and swarmed down Naval Trench, either killing or capturing the garrison up to the Gavrelle road.
About the same time the block on the left of the line, near Thames Valley, was forced by the enemy, and the whole of the Naval Line was in his hands. But the Queen’s Westminsters, gallantly led by Col. Glazier, were still in front of the Germans on the line Keiller, Pelican, and Thames Posts. Every bit of the communication trenches which gave a good fire position, every dump-hole, even the shell-holes were manned, and, as the Germans advanced over the open, in reorganised lines, from Naval Trench, they were met with a fresh rattle and roar of rifle fire. The ground was covered with silent and groaning figures in the field-grey uniform, and the enemy had to resort once more to bombing.
Again the Queen’s Westminsters gave up a little ground, but the enemy’s effort was smashed. At 11 a.m. the position was: we held a block in Towy Alley, about 300 yards east of the Ditch-Bailleul East line, and Castleford Post, and the rest of the battalion had joined the 2nd London Regt. in the Bailleul-Willerval line.
The account given by the London Rifle Brigade on the left of the Queen’s Westminsters is short, but in it one can read the desperate nature of the fighting and the gallant resistance which was put up. The relief of Bradford and Bird Posts was not completed until 3.30 a.m., when the bombardment which heralded the attack commenced. All forward and lateral communication was at once cut. Wire and posts defending the front line were wiped out. When the enemy infantry advanced, they simply walked into the front line, rushed the few men left at the blocks in Belvoir and Brough, and commenced bombing towards Naval Trench. The battalion was almost annihilated, and what was left joined the Queen’s Westminsters in Thames Valley and became mixed up with them. The fighting strength of this battalion at the commencement of the battle was 23 officers and 564 other ranks; it was reduced to 8 officers and about 60 other ranks.
The whole of the 169th Brigade now stood on the Bailleul-Willerval line and the enemy was held. Twice he attacked over the open, with aeroplanes flying low and pouring a hail of bullets on the defenders, while field guns were dragged by plunging horses and straining men across No Man’s Land as far as Naval Trench, but each time he was defeated. The field guns fired no more than twenty rounds before being silenced by the 56th Divisional Artillery; and though the enemy infantry had a novel method of advancing—they stood up, threw their rifles forward into a shell-hole, held up their hands, and advanced, only to drop by the side of their arms, which they immediately proceeded to use—they made no further progress.
The right of the 56th Division was, at 11 a.m., in touch with the 4th Division. A battalion of the 167th Brigade was placed under the orders of the 169th, and six machine guns were sent up to Point du Jour, and two field companies of the Engineers to Tongue and Blanch Posts, so that the right flank of the division seemed secure.
The 4th Londons, on the right of the 168th Brigade, put up a most gallant defence. Wood Post, held by 2 officers and 45 other ranks, had been moved before the bombardment and so was untouched. The full garrison was there to meet the enemy, who advanced in a solid line on the left of the wood, but came through the wood in groups of about ten men each, 40 yards or so apart, and followed by further groups of about thirty men each some 200 yards in rear.
The enemy was completely checked in the wood and on the left; but Beatty Post, on the right, which had been badly battered about by trench mortars, was occupied. The garrison, consisting at first of 3 officers and 84 other ranks, though much depleted when the assault was launched, was overwhelmed by sheer numbers, and only 1 officer and 6 men ever returned. The enemy then started to work round to the rear of Wood Post, but for over an hour this hard little band held out and repulsed the enemy.
Oppy Post was also smothered by artillery and trench mortars, and eventually overwhelmed by the storming infantry. Of the 2 officers and 48 other ranks forming the garrison, 1 officer and 5 other ranks were left.
Fifteen minutes after the assault was launched, the enemy was in the Earl Lane and Viscount Street, but were held for a time by the troops in Ouse Alley. But so long as Wood Post held, the enemy did not make any great progress.
Major F. A. Phillips was in command of the forward fighting, and moved about encouraging his men, who were inflicting heavy casualties on the enemy whenever an attempt was made to advance over the open. But Wood Post fell back just before 9 o’clock, and soon after the enemy began to force their way up Ouse Alley from Viscount Street, in rear of the troops who were fighting so successfully in Marquis Trench. Major Phillips promptly attacked over the open with about twenty details from headquarters, and drove them back.
The enemy had built up heavy rifle fire from Oppy Wood, although he was suffering severely there from our artillery fire, and attacked the left of the battalion many times over the open; but the Marquis line held, and at 11 o’clock the position was extraordinary. The 169th Brigade on the right was back in the Bailleul-Willerval line; and while the advance companies of the 4th London were still holding the Marquis line, the enemy was in Ouse Alley and bombing his way towards the Bailleul line, also he was advancing over the open south of Ouse Alley. The position then was very precarious, and the reserve company, which Colonel Marchment had sent to get in touch with the forward troops and form a flank, was unable to reach the forward troops. Major Phillips decided to withdraw.
The withdrawal was witnessed by Colonel Marchment from his headquarters:
“I watched it through my glasses. It was carried out in a very steady and orderly way, the men leaving in groups of about a dozen. Although exposed to a heavy fire from front and flanks, they made excellent use of the ground, and suffered very few casualties.... The men of the reserve company met the survivors returning and covered their retirement.”
The Kensingtons on the left of the division were not attacked. Some fifty of the enemy approached Tommy Post, but were at once driven off with casualties. But the battalion gave invaluable aid to the 4th Londons, on the right, inflicting heavy losses by Lewis gun, rifle, and rifle grenade fire on the German support troops as they came up to the wood. About 11.30 a.m. the battalion was ordered to retire, in conjunction with the right of the 3rd Canadian Division, on the left, and so came into line with the rest of the division.
The intense anxiety at Brigade and Divisional Headquarters can best be imagined. For the first two hours of the battle little news could be gained from Battalion Headquarters as to the progress of the fight. The whole battlefield was enveloped in smoke, and interest was chiefly centred on the fine stand which was being made by the Queen’s Westminsters at Towy Post, where a power buzzer was installed, and messages were received from the signallers even after the capture of the post. At one time, while the 4th Londons were still holding the front-line system, the enemy was attacking Bailleul East Post, held by the London Scottish, and had captured two machine guns with crews just in front of the post. A well-timed counter-attack from this gallant regiment drove the enemy back and released the guns and crews.
As the smoke cleared from the field, the Divisional Artillery took every advantage of their well-situated observation posts. But, though the struggle was going on before them, observers found that both sides were frequently so mixed up that they could give no help. Small bodies of our infantry could be seen clearly, fighting with Germans on all sides of them.
On the right the situation of the 4th Division was very obscure. The division was reported to have lost touch with its own brigades, while the lateral line between the 169th and 12th Brigades was also cut.
With the withdrawal of the 56th Division to the Bailleul-Willerval line the situation cleared. They were then in touch with the 4th Division, and the artillery was able to put down a protective barrage in front of this line. The 3rd Canadian Division gave valuable assistance with nine 18-pounders.
8. The First Battle of Arras 1918.
“From this time till about 3 p.m.” (writes Brig.-Gen. Elkington), “many excellent targets in the open were engaged by both field and heavy artillery with great effect. Unfortunately, owing to the limited number of guns available, and that many had to be used for the immediate protection of our infantry, only a few could be used for the excellent targets in the open. At about 3.30 p.m. the enemy made a heavy attack against the Bailleul line, particularly on Bailleul East Post; this was completely shattered by a concentrated barrage and by rifle and machine-gun fire. With the exception of hostile bombing attacks up the communication trenches leading to the Bailleul line, the enemy made no further serious effort to attack. All battery positions were heavily shelled throughout the day by all calibres of ordnance, the shelling being more of the nature of area shoots than definite counter-battery work. As a result, from dawn on the 28th to dawn on the 29th twelve 18-pounders were destroyed or put out of action by enemy shell-fire. In addition two 18-pounders in position as an enfilade section near Arleux, facing south-east, had to be destroyed and abandoned when our line was withdrawn to the Bailleul line. This section engaged many targets with observation from the vicinity of the guns, and was fought until our infantry withdrew through it. The detachments then retired after damaging the guns, burning the dug-outs, and removing dial sights and breach blocks. All the six 6-inch mortars in the front line were lost to the enemy, and no news was available as to the fate of the officers and detachments of the two that were manned (they were afterwards found to have been made prisoners).... During the night of the 28th/29th, with the exception of two batteries, all the Divisional Artillery was withdrawn to positions at an average of about 3,600 yards to our new front, this move being carried out by single batteries in turns.... The ammunition expended from the early morning of the 28th to the early morning of the 29th by the 56th Divisional Artillery alone was: 23,000 rounds of 18-pounder and 8,000 rounds of 4·5 howitzer.... As a result of an urgent request to the Corps on the afternoon of the 28th for new guns to replace the damaged ones, six new ones were sent up—these turned out to be 15-pounders, for which we had no ammunition.... The Germans in their official communiqué reported that the 56th Division had been annihilated!”
The German attack was definitely crushed in the morning, but during the afternoon a number of half-hearted and tentative attacks were made. The situation, however, became more quiet about 6 p.m., and the 169th Brigade was relieved by the 167th, with the 5th Canadian Mounted Rifles in support at Point du Jour.
During the night the engineers were employed in blocking and filling-in the communication trenches in front of the new line, and patrolling was actively carried out. The Kensingtons penetrated into Arleux Loop South, Kent Road, and the junction of Tommy and Baron, which seems to show that the enemy were dazed.
On the 29th, except for some demonstrations at the bombing blocks, the enemy made no move. There were many reports that he was massing for further attacks, but it became evident that he was relieving his storming troops. As night fell, the first platoons of the 4th Canadian Division started to relieve, and during the night the 167th Brigade moved back to Villers au Bois, the 168th to Mont St. Eloi, and the 169th to Ecoivres.
On the 30th General Dudgeon visited the First Army Headquarters, where he was congratulated by His Majesty the King.
There is little doubt that the enemy hoped to achieve great results by this new stroke, and that its failure was a serious set-back. Five divisions attacked the 4th and 56th Divisions north of the Scarpe and, according to captured documents, when the line Vimy-Bailleul-St. Laurent-Blangy had been won, three special divisions were to attack and capture the Vimy Ridge on the following day. South of the Scarpe eleven divisions were launched, with the object of capturing Arras and carrying the attack as far south as Bucquoy. The German official list (published 1919) gives eleven divisions attacking north and south of the Scarpe, one division at Neuville Vitasse, and one at Moyenneville—thirteen in all. It makes no mention of an attack south of Moyenneville. But the eleven which attacked on the Scarpe were beaten by the four British divisions which held that line—the 4th and 56th on the north, and the 3rd and 15th on the south.
From this date onward the great German offensive began to decline, and ended in the Somme area with a final effort to separate the French and British Armies on the 4th and 5th April, by an attack on the north and south of the Somme. “It was an established fact,” says Ludendorff, “that the enemy’s resistance was beyond our strength.” Strategically the Germans had not won what the events of the 23rd, 24th, and 25th March had led them to hope for—the failure to take Amiens was a great disappointment.
The total casualties of the division were 55 officers and 1,433 other ranks—not excessive, considering the weight of the attack and the immortal triumph gained by the 56th Division. The importance of this battle is so great that we give the comments of the two brigadiers.
Brig.-Gen. Coke says that during the six weeks his brigade had been in the line, the Cheshire Regt. had worked splendidly, and had put up double apron belts of wire where they would be most effective—the Naval-Marine line was protected by five belts of wire—and this stood the bombardment well enough to be a serious obstacle. When the smoke, which had enveloped the field at the commencement of the battle, had cleared, excellent observation was obtainable, and the divisional observers and artillery observers did splendid work. The enemy batteries, which came into action in the open during the afternoon, were brought up under cover of smoke, and started to fire point-blank at the Bailleul line, but the Divisional Artillery silenced them in a few minutes. There was no shortage of ammunition or bombs. The system of keeping a plentiful supply in deep dug-outs proved sound.
“All concerned are convinced that the enemy losses were extremely heavy in front of this brigade. The fullest use was made of Lewis guns and rifles, and every attempt of the enemy to advance on the Bailleul line over the open was checked by these means. The fire-bays constructed along Towy Alley proved specially valuable, and very considerable losses were inflicted on the enemy from them during our withdrawal to the Bailleul line.
Many officers testify to the gallant way in which the Machine Gun Battalion served its guns to the last and to the good results of the machine-gun fire.
Our artillery inflicted the maximum amount of damage possible. The number of guns available for the brigade section was quite inadequate to cover effectively such a wide front. But the infantry testify to the heavy losses inflicted on the enemy owing to the quick way in which the group and battery commanders engaged each good target as soon as it was observed.
Gallant work was done by the 169th Light Trench Mortar Battery during the day. Three of the teams disappeared with the garrisons in the left sector. During the withdrawal, mortars were placed to cover Pelican and Bailleul Posts.”
It was widely noticed by the men of this brigade that the enemy approached in a slow, dazed manner. The brigadier thinks that this may have been due to the great weight carried by the German infantry, who seem, amongst other things, to have carried a week’s rations. The enemy advanced in three or four lines and almost shoulder to shoulder.
Brig.-Gen. Loch sent in a frank and interesting paper, in which he points out:
“(a) The uselessness of locking up large garrisons in the front-line posts which are clearly known to the enemy and are within effective trench-mortar range. Front-line posts should be held lightly, and be used as observation posts and to keep the enemy patrols from approaching our main line of defence. They should be carefully concealed, need have no regular communication trenches, and should be frequently changed. The garrisons should be small and frequently relieved. If rushed and captured from time to time, little harm is done, provided the garrison have no identification marks. Deep dug-outs in such posts are a positive danger and should not be allowed; shelters against the weather are ample. If heavily attacked, the rôle of such posts should be to put up the S.O.S. and withdraw. The sole exception to this rôle is in the case of posts whose whereabouts can be properly hidden from the enemy. Such posts can be strongly garrisoned and may have machine guns, as they will have to break up and delay an attack. The losses in the forward posts are sufficient commentary on the unsoundness of the (present) system.
(b) The value of changing the actual position of the garrison in any post–vide Wood Post.
(c) The grave danger of altering carefully thought-out dispositions at the eleventh hour. On the evening of the 27th inst. my dispositions, which had been most minutely worked out to meet the situation of an attack on my right flank at the junction with the left of the 169th Brigade, about Viscount Street, and covering Bradford and Mill Posts, had to be changed as the result of orders, and consequently this portion of the line (always weak) was rendered hopelessly incapable of withstanding a strong attack. It is recognised that larger questions were involved, and no doubt decided the redistribution, which was not complete before the attack developed.
(d) The uselessness of Stokes mortars in the actual front line. Such weapons can only open on their S.O.S. lines, and are very vulnerable from attacks on the flanks. The four forward guns only fired about 50 rounds before being surrounded. Had they been behind the main defensive line covering the communication trenches, and themselves covered by the infantry, they would have been far more valuable, and would not possibly have been overrun.
(e) The value of trench blocks was fully found out. Such blocks should be prepared ready against penetration laterally, so as to localise it.
(h) Previous rehearsals and thorough knowledge of overland routes are essential. To the fact that these points had received proper attention is attributable the successful delaying action of this brigade.
(i) Defensive flanks prepared as such are invaluable.
(j) Infantry and machine guns must establish closer liaison.... It should be recognised once and for all that all machine guns in a brigade sector must come under the senior machine-gun officer in that sector.... Nothing herein said, however, should be permitted to detract from the principle that the battalion commander can and should issue orders to the guns covering him if he considers the situation demands it....
(k) Main forward communication trenches should never be traced to lead into strong points.... Such communication trenches are mere covering approaches to these strong points and afford easy access to the enemy. Our main battle zone should not be covered by a single trench, e.g. the Red Line (Bailleul), but should consist of at least three trenches with strong points so constructed as not to be apparent and obvious. As with garrisons of forward posts, so with garrisons of battle trenches, they should be constantly moved so as to avoid giving away the position actually held.”
A captured German officer of the 152nd I.R., 41st Division, gave as the main causes of the failure of the attack (a) the intensity of the machine-gun barrage, which caused heavy casualties. His regiment lost 12 officers and the 16th I.R. lost 24 officers; (b) watches did not appear to have been correctly synchronised. We have mentioned the service rendered by the Machine Gun Battalion, but, unfortunately, there is no record of Lieut.-Col. E. C. S. Jervis’ dispositions. This gallant and able officer says that the “tender spots” in his defence were the low ridges running due east and west through Bradford Post, and from Mill Post, south of Belvoir Alley, and then west. The former could not be covered by machine-gun fire, the latter was. And we know that the enemy, having exterminated the garrison, were mown down, in and round Gavrelle, from the indirect fire of fourteen machine-guns.
