"Let us choose sides," suggested Ben. "Instead of having an Army of the North and an Army of the South, we can have——"
"An Army of Red and an Army of Blue," finished Dave. "What do you say to the red sweaters against the blue sweaters?"
As many lads of the school wore red sweaters, and about an equal number wore blue, the idea caught on instantly, and at the noon recess the two armies, of Red and of Blue, were hastily organized. Each numbered twenty-five recruits, and Roger was made the leader on one side and Sam Day the leader on the other. With Roger went Dave and Phil, while Ben, Buster, and Shadow sided with Sam. Roger's side was the Army of Red, and they made themselves a big red flag, with the initials O. H. on it. Not to be outdone, Sam's army made a big blue flag, also with the school initials.
It was decided that the Army of Blue was to take a position in the woods, and that the Army of Red was to try to dislodge them and force them to retreat. If either army was driven back two hundred yards it must give up its flag and count itself beaten.
After school half an hour was allowed for getting ready, and most of that time was consumed in making snowballs and in fortifying the edge of the woods by throwing up a snowbank. Then a bugle belonging to one of the students sounded out, and the great snowball battle began.
It was certainly a hot contest, and the snowballs flew in all directions, and many a "soldier" received one in the body or in the head. Sam had placed his followers with care, and try their best the Army of Red could not dislodge them.
"I have a scheme," said Phil, after the battle had lasted for fully half an hour, and while the boys were pausing to manufacture fresh "ammunition" in the shape of snowballs. "Let us rush up and then pretend to retreat. They'll think they have us on the run, and as soon as they leave the woods and that snowbank, we can turn on 'em again, and wallop 'em."
"If you try that, be sure of one thing," said Dave. "Have plenty of snowballs on hand. Otherwise that fake retreat may become a real one."
"We'll make a lot of snowballs," said Roger. "Pitch in, everybody!"
In a little while, the Army of Red was ready for the movement Phil had suggested. Then Roger explained just how it was to be carried out. They were to advance on the left wing of the Blues and then retreat in the direction of the road. As soon as the Blues came from cover, they were to drive them—if they could be driven—to the upper edge of the woods and across the field beyond.
