One of the most sanguinary encounters that I was ever in happened during the latter part of April. My company was doing duty in brigade support line which was a captured trench we had taken from the Germans. It was now being used by us as an observation trench. It ran along the slope of the ridge, and from it we could see the smoke coming out of the chimneys of the coal mines at Lens, about four and a quarter miles away. A splendid view of the ground occupied by the Hun could be had, as his trenches lay in front of us. One day about 4.30 P.M. we received information that the Germans were assembling in a certain sunken road with the view of making a counterattack. Our artillery had been given instructions to concentrate their fire at 5.30 P.M. upon this road. Excitement ran high in our trench and we were all anxious to be at the Huns again. Everyone that could was looking through periscopes and some peered over the top of the parapet as we eagerly waited for our artillery to commence. At 5:30 P.M., much to our surprise, our artillery did not open up. We suspected that the Germans had by some means found out that we knew they were assembling for this counterattack and that they therefore gave up the idea. That even at dusk we prepared to advance, but during our stay in the observation trench we had five casualties in our company. We were to occupy a lately evacuated German trench which was directly in front of our firing line. The battalions on our right and left flank also had to move up. At 10.00 P.M. we left the observation trench and were met by guides from the battalion which was then holding the sector of the front line trench that we had to pass to get to the recently evacuated German trench, now to become our front line. With my guide I led my platoon in single file for a distance of 50 yards past the firing line. All at once the Germans commenced to bombard us with gas shells. We immediately put on our gas helmets and advanced through these poisonous fumes. When we were within 200 yards of our objective the Huns put up what we call a box barrage. They had evidently been warned of our advance. A box barrage is shell fire directed along the rear and both flanks. It hemmed us in, although the flanking fire did not harm our company, as it was too far away from us, still the fire from the rear was gradually creeping up to us, and it was a very anxious and trying time for our nerves as it came gradually towards us. I shouted out to form line in extended order and we made a rush for our objective, which we had named "Winnipeg trench." We managed to get into it in the nick of time, as the creeping barrage was almost on top of us.
