The grand soldiers are not comprised in those of one side, any more than the other. Here is a sample of an unknown southerner, a lad of seventeen. At the War department, a few days ago, I witness'd a presentation of captured flags to the Secretary. Among others a soldier named Gant, of the 104th Ohio volunteers, presented a rebel battle-flag, which one of the officers stated to me was borne to the mouth of our cannon and planted there by a boy but seventeen years of age, who actually endeavor'd to stop the muzzle of the gun with fence-rails. He was k**'d in the effort, and the flag-staff was sever'd by a shot from one of our men.
