One of the bravest exploits of the many performed during the struggle was that of Sapper Harmon of the 1st Field Company, C. E., one of a party of twelve sappers and fifty infantrymen of the 3d Canadian Battalion, which had constructed a barricade of sandbags across a road leading to the Orchard while under heavy fire. The Germans later smashed the barrier with a shell, and Harmon wormed his way forward and repaired it while a machine gun not more than sixty yards away was pumping bullets into the barricade. Of Harmon's party which went out to build the obstruction, six of the twelve were killed, and of the infantry, out of fifty, six were killed and twenty-four wounded. Sapper Harmon continued his dangerous and useful work in the Orchard, where alone and unassisted he worked for thirty-six hours digging tunnels to serve in subsequent operations. A short time after the capture of the Orchard the Canadians played a little trick on the Germans that cost the latter many casualties. While the Canadian artillery hammered a section of their line, a great show was made of preparing to attack as soon as the firing ceased. As was their usual custom the Germans fell back on their support trenches ready to rush forward when the bombardment ceased and meet the Canadian attack. The operation did not develop exactly as they expected, for after the guns shifted from the front trenches and shelled the supports, and the Germans notwithstanding pushed forward and occupied the front trenches the Canadian infantry did not attack. They stood fast while their guns shortened range and the enemy crowded in the front trenches received the full blast of a devastating fire. The German wireless on the following day reported that a heavy Canadian attack had been repulsed. Early in the evening of May 20, 1915, the 13th Battalion (Royal Highlanders), commanded by Lieutenant Colonel Loomis, moved across the British trenches under intense shell fire that caused heavy casualties, in support of the 16th Battalion Canadian Scotch. Three companies of the 13th Battalion (Royal Highlanders), after the Orchard had been won, now marched forward under Major Buchanan, who replaced the commanding officer, who was severely wounded. A fourth company advanced and occupied a support trench in the immediate rear. The position having been consolidated, the weary but elated 16th Battalion, which had performed such brilliant work, withdrew from the scene. North of the Orchard the Germans made a demonstration in the afternoon of May 21, 1915, but the fire of the Canadian artillery dispersed them. The Germans did not attempt to attack during the night though they kept up a constant musketry fire. Canadian working parties by the light of German flares were busy improving the position, which they left in excellent condition when the 3d Toronto Battalion of the First Brigade relieved the Royal Highlanders.
