The troops received their instructions under a sun which was shining for the first time in days. The men knew almost as well as their commanders the difficulty of the task and realized how well-nigh impossible its accomplishment would be. Yet they never doubted or hesitated.

The orders were to send over one brigade first—and if it failed, to send another—and others, one after the other—if it became necessary. It was with the dash that is traditional in the American army that the Yankee troops tackled the problem. Theoretically they had the choice of crossing anywhere for five miles. Actually they were limited to one point, where two-thirds of a mile of mud lay between the river itself and the canal that roughly parallels the river.

The Germans were too firmly intrenched at all other points. They had not protected themselves with trenches here because they never dreamed the Americans would be so daring as to try to force the passage. This was a short distance north of Velliers.

First came the call for swimmers from the first brigade. Not a man who could swim a stroke failed to stand out when the call came. Those whom their officers thought fit were put in the van.

With these went Hal and Chester.

It was intended to attack in this way on the theory that the swimmers were less likely to be hit by the Germans, owing to the fact that they would be nearly submerged. On the other hand, they would carry with them ropes and other paraphernalia for assisting men across who were unable to swim.

A perfect rain of fire from the Germans met these first Americans, as, under command of Captain Donaldson, Hal and Chester, they waded into the stream. The enemy had ensconced himself up the east bank with carefully selected machine gun positions, which raked every point of the bank where efforts to land could be enfiladed or met with direct fire.

Some men were killed in the water. More were drowned after having been wounded, for no unwounded man dared stop to rescue a comrade if the maneuver were to be successful.

Captain Donaldson made no effort to keep his men in formation as they swam rapidly across the river. There would be time enough for formation when they were safely ashore. Each man, when he waded into the water, struck out for himself, his chief aim being to reach the opposite shore as quickly as possible.

No bullet touched Hal or Chester as they swam at the head of their men. Bullets kicked up the water all about them, but both lads seemed to bear charmed lives.
