Cut off from their supports, a handful of defenders under a lieutenant made a gallant defense of this important position. “Hill 60” will ever be famous for the heroic deeds of Princess Patricia’s Light Infantry in 1915.] In the spring of 1915, a Canadian cavalry brigade was formed in France made up of Strathcona’s Horse, King Edward’s Horse, the Royal Canadian Dragoons and Canadian Mounted Rifles. After the second battle of Ypres, the Canadians after resting and re-organization, were moved to a section of the line near La Bassée. Here they fought the battle of Festubert--a series of infantry attacks and artillery bombardments, which gained little ground. Shortly afterwards they fought the battle of Givenchy, equally futile, as far as material results were concerned. Both of these battles had the double object of feeling out the strength of the German line and of obtaining the Aubers Ridge, should the attacks prove successful. In both battles the Canadians showed great aptitude for attack, and tenacity in their hold of captured trenches. They also learned the difficult lesson that if an objective is passed by the infantry the latter enter the zone of their own artillery fire and suffer accordingly. In September, 1915, the Second Canadian Division arrived in Flanders and took its place at the side of the First Canadian Division, then occupying the Ploegsteert section in front of the Messines-Wytschaete Ridge. The rest of the winter was spent more or less quietly by both divisions in the usual trench warfare, and battling with mud, water and weather. It was here that the Canadians evolved the “trench raid,” a method of cutting off a section of enemy trench, killing or taking prisoners all the enemy inhabitants, destroying it and returning with little or no loss to the attacking party. This method was quickly copied from one end of the Franco-British line to the other; it proved a most valuable method of gaining information, and served to keep the troops, during the long cold winter months, stimulated and keen when otherwise life would have proved most dull and uninteresting. The Third Canadian Division was formed in January and February, 1916. One infantry brigade was composed of regiments which had been acting as Canadian corps troops, including the Princess Patricia’s Canadian Light Infantry, and the Royal Canadian Regiment. The second infantry brigade was made up of six Canadian mounted rifle regiments, which had comprised part of the cavalry brigade. These two brigades, of the Third Division, under the command of General Mercer of Toronto, almost immediately began front-line work.
