Next to Peter Lambton, Harold's greatest friend in the corps was a young man named Harvey. He was of good family and belonged to New York. Being a strong loyalist, he had, like many other gentlemen, enlisted for service under the old flag. He had, naturally, many acquaintances among the county families, and Harold often accompanied him in his visits to one or other of them.

During the winter, when things were quiet, the duties of the scouts were light, and it was the habit among them that one-third should be on outpost duty at a time, the rest being free to move about as they liked. The scouts had no fixed order of position. They went out alone or in twos or threes, as it pleased them, their duty simply being to watch everything that was going on along the enemy's line of outposts, to bring the earliest news of any intended movements, and to prevent dashing parties of the enemy's horsemen from making raids into or behind the British lines. They were not, of course, expected to check bodies of cavalry starting on a raid, but simply to obtain information of their having left their lines and of the direction taken, and then to hurry back to the British posts, whence a force of cavalry would be sent out to intercept or check the invaders. Many dashing exploits were performed by the cavalry on both sides in the way of getting behind their opponents' quarters, cutting off provision trains, attacking small posts, and carrying off straggling parties.
