What a cool story! I never knew of this prayer.
I like General Patton-old 'Blood and Guts'. My kind of general!
He liberated Orleans, France, you know; the city that St. Joan of Arc liberated from the English in the Hundred Years' War. When I was in Orleans in 1985, I saw a small memorial in front of the Town Hall (next to the Cathedral of the Holy Cross) that marked the spot where Patton announced the city's freedom from the Nazi tyranny. In fact, May 8th, the day that St. Joan raised the siege of Orleans in 1429, was the day that World War II in Europe ended.
