Cruising along the coast, now in the ‘Vauban,’ now in the ‘Wasp,’ Lieutenant Lempriere and his men landed for short intervals at Pitsunda, Soukum Kaleh, Redoubt Kaleh, Anacrea, Churuksu, Batoum, and lastly, all went up to Trebizonde. The two Kalehs were the fortresses at which the services of the sappers were chiefly given. At Redoubt Kaleh two men who had been left by Captain Stanton as overseers to the Turks joined Lieutenant Lempriere’s little force. In addition to instructing the Ottoman soldiers in the mode of forming fieldworks, the sappers superintended the restoration of some old batteries and revetments, the construction of various new defences, and assisted Lieutenant Lempriere in the surveys be found it necessary to make for professional purposes. While they were thus busy, the Crimean Expedition had been determined on, and as every sapper was wanted for the enterprise, the party was recalled and rejoined the corps just as the siege was about to open. Corporal John Pendered and lance-corporal John Hammond arrived at Varna on the 24th July, and were attached as photographers, under Captain Hackett, 77th regiment, to the head-quarters of the army. Previously to leaving London they had been instructed in the art by Mr. Thompson, and had practically tested their efficiency at Chatham, where patches of broken ground, and military scenes and fortifications, gave them a variety of subjects to portray. Many of their photographic sketches, taken under circumstances of difficulty and disadvantage, were exhibited at Gore House during the summer months; but without having the chance of proving their usefulness and skill, these two young men, promising and enterprising, perished in a storm.
