Report of Rear-Admiral Dahlgren, U. S. Navy
Flag-Steamer Philadelphia
Off Morris Island, November 17, 1863.
Sir: I beg leave to call your attention to meritorious service, under a severe fire of the enemy, by certain persons of this service. ....
With pleasure I bring to your notice the gallant behavior of Acting Ensign R. Burk, who was severely wounded, and also of the Medical Officer of the Lehigh, Dr. W. Longshaw. Twice he passed in a small longboat to the Lehigh from the Nahant, carrying a line bent on the hawser. The shots and shells from cannons and mortars were flying and breaking all around. The third time this service was performed by Horatio Young, William Williams, and Frank S. Gile. These I advanced on the spot in their rates. I have also give appointments as [acting] master's mates to the two petty officers who rowed Dr. Longshaw - George W. Leland and Thomas Irving.
It would have also been very gratifying to me if it had been in my power to advance Acting Ensign Burk and Dr. Longshaw under the fire, when they so well performed their duty, and by which the former had been severely hurt, for a recognition of this kind has always been more valued in military service than any other. I beg leave to recommend them to the notice of the Department, with the observation that they risked their lives to save an invaluable vessel, which, I am glad to say, sustained no great damage. ....
