His compass sold last month on E-Bay. Admin has added his memorial plaque to the forum, so you can see the rank he achieved. I've got a photograph and a couple engravings of him, but my scanner is down at present.

In Zululand Throughout the War of 1879 by Norris Newman:
On Tuesday 18th another Naval Brigade was landed from the ‘Boadicea’, which had lately arrived to take her place as flag-ship of the Cape station, instead of HMS ‘Active’, ordered home; and on the next day the 57th and 91st Regiments both sent off large detachments en route for the Lower Tugela. They proceeded to Saccharine Station as far as the coastline then extended, a distance of about twelve miles from Durban, and then marched the rest of the way (fifty-two miles.) Thursday saw the departure of the Naval Brigade of HMS ‘Boadicea’ in a pouring rain. It numbered 238 men, who had with them one Gatling Gun, and one field piece, the men being armed with Martini-Henry Rifles. They were, as most men of all the Naval Brigades are, a fine, sturdy lot of fellows, and left in the highest of spirits. Lieutenant F R Carr was in command, and the other officers were Lieutenants E C Hobkirk, J B Benett; Sub-Lieutenants H F Lyon, H Coachworth; Midshipman Warrener, Honourable Colville, Hewitt, and Cruikshank.
His brother also served in campaign, as one of the draft replacement officers for the 1st/24th.
