This photograph was almost certainly taken in July, 1869, at the port of Villefranche. Paymaster H. P. Tuttle is standing second from left, not third from left. Alexander Slidell MacKenzie was killed two years before this group convened. In the photo is Lieutenant Morris R. S. MacKenzie, who served with Tuttle on the USS Guard, 1868-69.
