"MY DEAR SIR: You will probably receive an official report of the losses in the Fifty-fourth Massachusetts by the mail which leaves to-morrow, but perhaps a word from me may not be unwelcome. I saw the officers and men on James Island on the thirteenth instant, and on Saturday last saw them at Brigadier-General Strong's tent, as they passed on at six or half-past six in the evening to Fort Wagner, which is some two miles beyond. I had been the guest of General Strong, who commanded the advance since Tuesday. Colonel Shaw had become attached to General Strong at St. Helena, where he was under him, and the regard was mutual. When the troops left St. Helena they were separated, the Fifty-fourth going to James Island. While it was there, General Strong received a letter from Colonel Shaw, in which the desire was expressed for the transfer of the Fifty-fourth to General Strong's brigade. So when the troops were brought away from James Island, General Strong took this regiment into his command. It left James Island on Thursday, July sixteenth, at nine P.M., and marched to Cole's Island, which they reached at four o'clock on Friday morning, marching all night, most of the way in single file over swampy and muddy ground. There they remained during the day, with hard-tack and coffee for their fare, and this only what was left in their haversacks; not a regular ration. From eleven o'clock of Friday evening until four o'clock of Saturday they were being put on the transport, the General Hunter, in a boat which took about fifty at a time. There they breakfasted on the same fare, and had no other food before entering into the assault on Fort Wagner in the evening. "The General Hunter left Cole's Island for Folly Island at six A.M., and the troops landed at the Pawnee Landing about half-past nine A.M., and thence marched to the point opposite Morris Island, reaching there about two o'clock in the afternoon. They were transported in a steamer across the inlet, and at five P.M. began their march for Fort Wagner. They reached Brigadier-General Strong's quarters, about midway on the island, about six or half-past six, where they halted for five minutes. I saw them here, and they looked worn and weary.
