Original Toronto Star caption: Impregnable, but captured--Here, until April 9, 1917, the German front-line twisted its sinuous way across the brow of Vimy Ridge, glowering down on and menacing the lower-lying Canadian trenches seen in the picture adjoining to the LEFT. [link to Good Housekeeping 3-SC-SU-243] So vital an anchor did the massive bastion provide or the whole line on the western front that the German high command had spared no no pains to convert it into an inland Gibraltar and felt confident they had made it impregnable. Nevertheless it was finally stormed and captured by the Canadian corps on April 9 in 1917.
