their proper place — were frequently seen, in all their glittering glory of a meter of bright and shining brass, sticking in the mud alongside the trenches where they had been thrown by the misguided individuals who had laboriously carried them up from the rear.
When we finally got up to the front, opposite Messines, we had a chance to work up some practical dope on machine-gun firing — indirect firing, I mean. The German position was along the Messines Ridge and ours on a similar height across the valley of the Douve River. The range, from crest to crest, was about a mile, but the front line trenches of both sides were advanced so that they were but some three hundred yards apart. From carefully concealed observation posts, along the crest, we were able to locate several important dumps and points of rendezvous within the enemy lines. The machine gun officer of the outgoing Surreys had begun this work and we took it up where he left off. There we used but one strafing gun, located just far enough back from the crest of the hill to be safe from direct enemy observation. Our maps were the accurate, official maps of the district, upon which had been printed a “grid” with squares of 1,000 yards further divided into quarters and these five-hundred yard squares marked with hatch-marks along the lines which were to be indicated by numbers, from one to ten, both horizontally and vertically, when describing the location of a target. By this system we could locate any target within a space of fifty yards and, by using an additional series of numbers, could bring this down to five yards. The contours were in meters.
Before doing any actual firing, we made range charts by using one of the regular maps and drawing on it the lines running from the gun position to the various targets, which were indicated by letters of the alphabet. The lines of sight were determined by compass and checked, whenever possible, by sending a man to the rear, where from some commanding height he could see both gun and target. Then another man, crawling out in front of the gun, drove a stake at the spot indicated by the observer, in a direct line from gun to target, and the letter of the particular target was plainly inscribed on the stake. The outgoing Surreys had already located several important points within the German lines. One of these, which we named “Cooker’s Halt,” was the place where the field or rolling kitchens came at night with the next day’s rations for the men in the front lines and where the ration parties gathered soon after dark every night. This was our first objective, and our initial night’s strafing was highly successful, as was evidenced by the dead horses and men and overturned cookers and limbers which were plainly visible there in the morning. That must have been a hot spot for Heinie for a few minutes. The shouting, screaming and general racket was plainly heard by the men in our front line and reported by them. From that time on their cookers never came over the hill, and we had to search for other targets. Occasional working parties were located and dispersed, and this furnished about all the entertainment; until, one afternoon, while scanning the enemy lines from one of our observation posts, I discovered a long string of motor trucks moving into the yard of a farmhouse where they unloaded boxes and bales of supplies, the character of which could not be determined at that distance.
After a little hurried work in figuring the range and direction we opened fire on them at a range of about 1800 yards — and how they did scatter. One truck, probably disabled, was left in plain sight but all the others quickly made their way back and over the hill, leaving some men lying on the ground.
During all the months that followed, both there and at other places along the line, we always maintained one or more strafing guns.
Practice with these not only inflicted a certain amount of damage upon the enemy but it qualified the men operating the guns for the more important work of delivering a harassing fire upon the enemy’s lines of communication during an engagement.
In connection with this strafing business I recall a funny incident. One day an officer of the Yorkshire Regiment happened to come down the communication trench just as I was entering it from a side trench which led to one of our strafing-gun positions. As I knew him to be the Emma-Gee officer of his unit, I invited him to go back with me and inspect the position, and I there explained to him just what we were doing in that line. Now he was a newcomer, recently out from England, and, while he had heard, in a vague way, of this kind of machine-gun work, he had never seen it tried out. I explained everything to him very carefully, showing our maps, range-charts and instruments. He had, it seemed, all the necessary equipment, and, becoming very enthusiastic, he vowed that he would surprise his commanding officer by starting something of the same kind in his outfit.
Well, he did, all right for that evening, just before dark, as I was passing along the trench which separated their sector from ours, I noticed a group of men mounting a machine gun some fifty yards behind their front line trench. Curious, I stopped to watch, and soon discovered my officer, busily engaged in giving instructions for the mounting and laying of the gun. He soon noticed me and came over. He was fairly bubbling over with enthusiasm and told me that he had received information from the F.O.O. of the local battery that they (the artillery) were going to strafe a certain cross-road at seven o’clock and that he was going to join the party with the gun which was just now being set up. On his map he showed me the location of the target and also all his firing data. I studied it awhile and then took a look at the terrain in the direction of the target, but said nothing. However, I made it a point to be around at seven o’clock and stood by while they fired four belts (1000 rounds) into the side of “Picadilly Hill,” about two hundred yards away. In figuring his firing dope he had made no allowance whatever for the difference in elevation. His target was on a high flat, some ten meters above his gun position, and with the edge of the flat — the hill mentioned — directly in front of the gun. With the gun and ammunition he was using it would have been a physical impossibility to hit the designated target from that point.
This machine-gun strafing was but one of the many innovations introduced by the Canadians. It was quickly taken up by all the others and soon became an established practice. Some units only used it occasionally, but we (of the 21st Battalion) made it a regular part of our business, and, having six guns instead of the regulation four, we were able to man all the usual front line positions and still have two guns left for strafing work. I hope that these lines may come to the notice of some of the men who were instrumental in providing those two extra guns, that they may know that their gift was a direct and important contribution to the fighting strength of the battalion.
All our original guns were Colts. I imagine I can hear some sniffs and horse-laughs.
We had breakages, of course, but probably no more than the fellows who were using the Vickers. Most of these troubles were caused, I believe, by faulty ammunition. Cartridges developing an excessive pressure will nearly always break something, and when you are using stuff which has been made in a hundred different little and hastily equipped factories and by girls who never before knew the difference between a bullet and a bodkin, why, what the hell can you expect? By experiment you adjust the retracting springs for some well-known and reliable brand of ammunition and the first thing you know, right in the midst of a fight, you get a bunch of the phoney stuff, and all at once something goes “flooey” and it’s a case of blow the whistle and take time out for repairs. Even the difference of a small fraction of an inch in the thickness of the rim of the .303 cartridge would break extractors as fast as they could be replaced. Various other irregularities, so small as to be un-discoverable with the naked eye, would cause stoppages and breaking of small parts. For the first few months, spare parts were practically unknown, and it required the utmost ingenuity on the part of the gun crew to improvise — and with what materials could be found
