Captain John Conn
The name is supposed to mean “Fearing nought but God”. Her captain later died at age 46 off Bermuda. He was commanding HMS Swiftsure and pursuing a French ship when he slipped and fell overboard.
Admiral Collingwood had his flag on the ship before the battle. The ship, however, was sluggish due to the formation of barnacles. He shifted to the Royal Sovereign, which had been sent for him from England under the command of John Penn. Perhaps due to his presence, Dreadnought reputedly had the most efficient gunnery crews in the fleet, and could fire 3 broadsides in 210 seconds.
Considering her achievements, Dreadnought got off very lightly, with just 7 killed and 26 wounded.
