"Yes," replied Chester. "Must be some momentous move under way."

Other officers now began to appear. They dashed up to the British commander, made their reports and immediately dashed away again.

"Lieutenant Paine! Lieutenant Crawford!"

It was General French summoning them and the boys approached and came to attention. Because of past experience, both lads realized instantly that the General had some ticklish work cut out and that he had selected them to carry it through.

"Take a troop of cavalry," came the command, "and make a reconnoissance of the northeast!"

Quickly two officers nearby sprang from their horses and offered them to the lads, for the latter had not yet had time to find steeds. The lads sprang into the saddle, saluted their commander, and dashed away. To the nearest cavalry force they hurried, where upon repeating General French's order to the commander, they soon had a troop at their disposal.

A troop of cavalry is composed of one hundred men. It is usually commanded by a captain.

Now it is very unusual for a commanding officer to have two lieutenants on his staff, as had General French in the persons of Hal and Chester; but the General had commissioned them as such on the spur of the moment, and when they took command of the troop they consequently, for the time, superseded the captain in command—for they were the personal representatives of the General himself.

The two lads placed themselves at the head of the troop and rode forward at a rapid trot. Past dense masses of infantry, battery after battery of heavy artillery and troop upon troop of cavalry they rode toward the northeast.

They were not yet at the front of the long battle line, for General French had his headquarters well back, but still close enough to be in constant danger from the enemy's artillery fire.
