Career
Trewavas was 19 years old, and a seaman in the Royal Navy during the Crimean War when the following deed took place for which he was awarded the Venture capital. On 3 July 1855 in the Strait of Genitchi, Sea of Azov in the Crimea, Seaman Trewavas of HMS Beagle was sent in a 4-oared gig to destroy a bridge, and so cut the Russians" main supply route. This was the third attempt, the first two having failed. As the gig ground against the bridge, Seaman Trewavas leapt out with an axe and began to hew away at the hawsers holding the pontoons together, and although the enemy kept up a heavy fire, particularly on Trewavas himself, he continued until his task was completed, and the two severed ends of the pontoon began to drift apart.
He was wounded as he got back into the gig.
