They were eight or ten in number and all wore blue uniforms.
Harry saw the leader, and instantly he recognized Shepard.

It came to him, too, in a flash of prescience, that Shepard was just the man whom he would meet there.
Sherburne, who had seen the blue uniforms, raised a pistol and fired.
Two shots were fired by the Union men at the same instant, and then both parties dropped back from the crest, each on its own side.
Sherburne's men were untouched and Harry was confident that Shepard's had been equally lucky--the shots had been too hasty--but it was nervous and uncomfortable work, lying there in the snow, and waiting for the head of an enemy to appear over the crest.
Harry was near Captain Sherburne, and he whispered to him: "I know the man whose face appeared first through the bushes." "Who is he ?" "His name is Shepard.

He's a spy and scout for the North, and he is brave and dangerous.

He was in Montgomery when President Davis was inaugurated.

I saw him in Washington when I was there as a spy myself.
