"Now then, all together!" cried the senator's son. "And make them think you are really retreating, at first."

Forward went the Army of Red, throwing snowballs wildly. Then came a shower of balls in return, and several of the Reds were seen to fall, as if knocked down. Then came a pause, and several lads started to go back.

"Stop! Don't run!" yelled Roger. "Don't run!" But as this was part of the deception, those in retreat kept on backing away.

"Hurrah! we've got 'em on the run!" came from the woods, and in a trice several of the Army of Blue appeared on the top of the snowbank. "Come on, let us chase 'em!"

Over the snowbank came the Army of Blue, carrying all the snowballs it could manage. The Army of Red continued to retreat, each boy loaded down with ammunition. Then, just as the edge of the woods was cleared, a loud whistle sounded out.

It was the signal to turn, and like one man the Army of Red faced about, and let fly a heavy volley of snowballs, directly in the face of the enemy. The Blues were taken completely by surprise, and almost dazed. Then came another volley of snowballs, and a dozen lads were struck, in the head and elsewhere.

"Wow!" yelled one boy. "Say, what are we up against?"

"Let 'em have it!" came the rallying yell of the Reds. "Down with 'em! Drive 'em to cover!" And on they came with a rush, throwing their snowballs with all the accuracy possible. The severe onslaught demoralized the other army for the time being, and two boys broke and ran—then half a dozen more—and then the whole army.

"Stop! Turn and face 'em!" yelled Sam. "Give it to 'em hot!" But this was not to be, for the reason that the Blues were out of ammunition. They ran close to the woods, but were driven from that cover by a flank movement, and then took to the field, trying to manufacture snowballs as they ran.

"We've got 'em going—don't let up!" cried Dave, and, having stopped to make a few more snowballs, he pushed on, with Roger and half a dozen others beside him. Phil carried the flag, and all made for where the enemy had its flag of blue. Then came an exchange of snowballs at close range, and poor Phil was hit in the face. He dropped the flag, and Dave picked it up.
