They should have kept moving. But the hardest lesson to teach in training, the most difficult rule to follow in combat, is to keep moving when fired on. Every instinct makes a soldier want to hug the ground. Cole's men did, and over the next hour the Germans dropped mortars on the battalion. The GIs were pinned down.

Then Cole could take no more and took command. He passed out an order seldom heard in World War II: "Fix bayonets!"

Up and down the line he could hear the click of bayonets being fitted to rifle barrels. Cole's pulse was racing. He pulled his .45 pistol, jumped onto the causeway, shouted a command so loud he could be heard above the din of the battle-"Charge!"-turned towards the hedgerow, and began plunging through the marsh.

His men watched, fearful, excited, impressed, inspired. First, single figures rose and began to follow Cole. Then small groups of two and three. 'Then whole squads started running forward, flashing the cold steel of their bayonets. The men began to roar as they charged, their own version of the Rebel Yell.

The Germans fired and cut down some, but not enough. Cole's men got to the hedgerow, plunged into the dugouts and trenches, thrusting, drawing blood and screams, causing death. Those Germans who dodged the bayonets fled to the rear. Paratroopers took them under fire and dropped a dozen or more.

Cole stood there shaking, exhausted, elated. Around him the men began to cheer. After the cheering subsided. Cole got his men down the causeway and over the bridge to the far side of the Douve River. There, the following day, Omaha and Utah linked up.

THROUGHOUT First Army, young men made many discoveries in the first few days of combat-about war, about themselves, about others. They quickly learned such basics as keep down or die, to dig deep and stay quiet, to distinguish incoming from outgoing artillery, to recognize that fear is inevitable but can be managed, and many more things they had been told in training but things that can only be truly learned by doing- in the reality of combat.
