I'm a Brit, and my Grandfather fought at Loos, La Boiselle and onward from there, but of all the WW1 sites that I have visited; the trenches at Vimy are quite shocking in their very close proximity - 40 yds in places. I've stood under the trees on the downslope from the Memorial and asked myself over and over again " How on Earth did they do it?" Huge Respect to them all.
