EDITOR BUFFALO EXPRESS: — Among the organizations that Buffalo sent to the "Wah" the gallant "Majah" Wheeler seems to have omitted G Co. 33d N. Y. Vols., which served in the erstwhile Army of the Potomac, and, as a body, certainly brought no discredit on Buffalo. Its first captain was Theodore B. Hamilton, son of Frank Hamilton, the celebrated surgeon and one of Buffalo's prominent citizens, who also served in the Army of the Potomac as Medical Director. Capt. Hamilton was promoted to Lieutenant Colonel of the 62d New-York after the peninsular campaign. Elery A. Eustaphteve was first lieutenant, but, owing to feeble health, had to resign and come home to die. His family were also among Buffalo's prominent people. George A. Gale the first orderly sergeant, was a typo in the Courier office, and succeeded Hamilton as captain. George W. Marshall was promoted from sergeant to first lieutenant, and was a Third - ward boy, brother to the present City Clerk, Charles Marshall George died a few years after the War from disease contracted while in the service. Hamilton and Gale are living; the former in New-York and the latter in the West.
