Yes, the date.....
I knew a Captain Vilhelm Kristjansson (from Vinnipeg, needless to say) who was overseas and at the Ridge when it was taken. He was, if I remember rightly, 44th B'n but he was working with the sappers, tunneling into the Ridge and setting the mines.
Funny thing he said was, "Mind you, Iwasn't a SOLDIER. Oh, certainly, I was a Captain and I was at Vimy Ridge and a number of other places but, in our outfir, you weren't regarded as a SOLDIER if you hadn't been at Regina Trench."
He also said that when they set off the main mine, the whole top of the Ridge lifted off and you could see Jerry and all his equipment, in bits and pieces, 400 feet straight up in the air. The mine was made up of about 20 tons of Ammonium Nitrate in 50-pound bags interspersed with 2-pound capped blocks of Trinitrotoluene. Part of his job was setting the mine itself.
He also said that the fuses for the big blast were laid by Pte. Zepherin Sioux, who rests with honour in the cemetery at the Sioux Valley Dakota Nation, 4 miles North of the Trans-Canada Highway, near the village of Griswold, Manitoba. I missed having a talk with Pte. Sioux by a single week; he passed away before our appointment.
44 B'n took some awful casualties, even at the Ridge, even with the mines and the Emma Gees. What a lot of people don't reallise is that both the British AND the French had tried to take the Ridge previously. Between them, they lost half a million men there. Then the job was turned over to the 'colonials'.... and they DID IT.
Two important factors often are missed regarding the Ridge: it was CURRIE, the overweight Canadian, who insisted that the Ridge COULD be taken, but ONLY if the troops were properly trained for THAT JOB. And it was Julian BYNG, the 'wild card' in the Imperial General Staff, who backed Currie all the way, got the canadians what they needed..... and gave CREDIT where it was due. Small wonder the troops decorated their trenches with 'Bing Boys' posters when they could get them: Byng had one up in his own dugout...... while every other general in the British Army was living in a chateau or a fancy hotel. Those two men, with the entire Canadian Corps working WITH them, got the job done. And nobody cared what language you spoke or what province you came from. Not after that. They were CANADIANS first.
I guess they're all gone, now. All we can do is salute them.
