Whilst awaiting a posting he remained aboard HMS "Captain" during the Battle of Cape St Vincent in February 1797. Although Berry had no specific duties during the battle, he again displayed his courage when Nelson came alongside the Spanish ship "San Nicholas" and gave orders to board her. Wrote Nelson, 'The first man who jumped into the enemy's mizzen-chains was Captain Berry, late my first lieutenant; he was supported from our spritsail-yard, which hooked in the mizzen-rigging... Having pushed on to the quarter-deck, I found Captain Berry in possession of the poop, and the Spanish Ensign hauling down'.
