by John Marshall, Royal Naval Biography — Tancock… (1823)
“ Tancock was strongly recommended by Sir James Saumarez to the commander-in-chief, who immediately ordered him to act as junior lieutenant of the Orion, in which capacity he commanded her launch, and gallantly supported Sir Horatio Nelson in his attack upon the Cadiz flotilla, July 3, 1797 [4] . He likewise fought under that immortal hero, at the mouth of the Nile, on the ever memorable first of August, 1798 [5] . ”
