Admiral Sir Hyde Parker (1739-1807) served in the British Navy in the West Indies and North America. He was mentioned in 1781 as a possible successor to Admiral Keppel as commander of the Channel fleet, but was not in fact promoted to Rear-Admiral until 1793, when Britain declared war on revolutionary France. At the Battle of Copenhagen in 1801, he signalled Horatio Nelson to disengage from the enemy fleet, but Nelson disobeyed him and went on to win the battle, giving rise to the story that Nelson had put his telescope to his blind eye and said “I see no signal”.
