Nor does he appear, as legend has it, to have been loved by his men: as commander of the Boreas frigate, during a commission which lasted 18 months, he flogged 66 of 142 seamen and marines: an extraordinarily high proportion. Careless of his own life, he was as careless of the lives of his subordinates. "My pride suffered," he wrote after the failure of an attack on the citadel at Tenerife in 1797. He mounted another, knowing it to be a forlorn hope. He lost an arm, but 148 officers and men lost the number of their mess. It was not the business of a rear-admiral - as he then was - to lead fewer than 1,000 men in a raid on a fortified citadel with a garrison of around 8,000. Hyperactivity, however, was as much to blame as pointless bravado. The former quality served him ill the following year, when the French fleet arrived in Alexandria only a few hours after his hurried departure. Had he delayed, he would have caught their transports and troopships, might even have captured Bonaparte himself - and decisively changed the course of history.
