“ Starting with a faint glimmering of knowledge acquired from Bogle, the old negro servant of a former baronet, who had accompanied him from Sydney, and aided by a most tenacious memory, the claimant succeeded in eliciting isolated facts which he used with startling effect. He took into his employment a couple of old carabineers, who had been servants to Roger Tichborne, and in a short time he was so completely master of small details of regimental life that more than a dozen of Roger's brother officers and an unlimited number of private soldiers were convinced of the claimant's identity. ”
