Vimy Ridge

It was at Vimy, in 1917, that all four Divisions of the Canadian Corps attacked simultaneously for the first time, about 100,000 men taking part in the battle. Vimy Ridge was an important part of the Germans' defenses, barring the way to the mines and factories in the Douai plain, which had been of great use to them in their continuation of the war. The very nature of the Ridge gave it strong, built-in defense, but these natural defenses had been supplemented by strong points, elaborate trench-systems and underground tunnels linking natural caves. All previous Allied attempts to capture the Ridge had failed, and there was a strong body of opinion among the Allied commanders that the Ridge was possibly impregnable and incapable of ever being taken by a direct attack. Preparations for the battle were thorough and extremely detailed. Behind their lines, the Canadians built a full-scale replica of the ground over which their troops would have to attack, giving all units the chance to practice their attacking movements and so understand what they (and neighboring units) were expected to do on the day. Regular reconnaissance patrols, assisted by information gathered from aerial photography, meant that records of changes to the German defenses on the Ridge were always up-to-date. Tunnellers dug "subterranean" passages under the Ridge - a total of five kilometers in all on four levels - allowing the attacking troops to move close to their jumping-off positions in some safety. Once the battle had begun, these same tunnels allowed the wounded to be brought back under cover and also provided unseen and safe lines of communications. The Infantry attack was preceded by a powerful artillery bombardment, which lasted almost three weeks, involving about 1,000 guns, including huge, 15-inch howitzers. For the first two weeks, some guns were not fired at all, so that the Germans would not be able to locate their positions but eventually, these guns joined in the bombardment, too. Although the shelling was aimed at the German trenches and defensive positions on the Ridge, the Canadians also shelled enemy batteries. They had become adept at locating German gun-positions and had identified the positions of 80 per cent of them. April 9th. 1917 - Easter Monday - dawned cold, with freezing rain and sleet. The ground conditions were very bad, with slippery mud waiting for hamper the Canadians as they began their assault. Heavily laden, the men began to cross the shattered No-Man's Land, skirting as best they could the shell-holes and craters, until they came to the muddy,
