In the last paragraph, a mention is made of "V H Peabody, HC", although the C is rather questionable. However, I can't think of any rank that matches HC, and the rank abbreviations online don't list any such rank - widening it to any rank beginning with a H, the only things on Naval History
are hospital related. A hospital rank seems unlikely, as the relatively small crew of the Albatross and low rate of injuries could presumably all be handled by the Surgeon - I'm not sure I recall seeing any crewmember suffer a major injury, nor are they likely to be involved in a shooting match, given that the ship's entire armament is 10 rifles and 9 revolvers.
Any thoughts on who he might be?
