"...we may no longer believe that God sends rain in answer to prayer; but that along the Rhine I found 250,000 men who believed - firmly believed- that God stopped the rain in answer to their prayers. Everywhere I went, men told me the story and showed me the cards. The only doubters seemed to be among the officers, especially a few chaplains; but there were no doubters at Patton's headquarters!"
"At any rate the rains stopped. They began to subside the morning after that prayer went to press on the evening before. 'Battle weather' came and stayed for an unprecedented ten days, during which General Patton's army swept the enemy back to the river and presently beyond."
