From Alex Kershaw, author of the New York Times bestseller Against All Odds, comes an epic story of courage, resilience, and faith during the Second World War

General George Patton needed a miracle. In December 1944, the Allies found themselves stuck. Rain had plagued the troops daily since September, turning roads into rivers of muck, slowing trucks and tanks to a crawl. A thick ceiling of clouds had grounded American warplanes, allowing the Germans to reinforce. The sprint to Berlin had become a muddy, bloody stalemate, costing thousands of American lives.

Patton seethed, desperate for some change, any change, in the weather. A devout Christian, he telephoned his head chaplain. "Do you have a good prayer for the weather?" he asked. The resulting prayer was soon printed and distributed to the 250,000 men under Patton's command. "Pray when driving," the men were told. "Pray when fighting. Pray alone. Pray with others. Pray by night and pray by day. Pray for the cessation of immoderate rains, for good weather for Battle. . . . Pray for victory. . . . Pray for Peace."

Then came the Battle of the Bulge. Amid frigid temperatures and heavy snow, 200,000 German troops overwhelmed the meager American lines in Belgium's Ardennes Forest, massacring thousands of soldiers as the attack converged on a vital crossroads town called Bastogne. There, the 101st Airborne was dug in, but the enemy were lurking, hidden in the thick blanket of fog that seemed to never dissipate. A hundred miles of frozen roads to the south, Patton needed an answer to his prayer, fast, before it was too late.
