In the U.K. and Canada it's Remembrance Day. Here in the States we call it Veteran's Day. But first it was Armistice Day, a commemoration of those who gave their lives, and a celebration of the end of the War to End All Wars.
Two poems for the occasion: "In Flanders Fields," by Lt Col. John McCrae of the Canadian Army, and "Dulce et Decorum Est," by Wilfred Owen, one of the best of the Great War poets. Both men died in 1918, just months before the armistice.
