Shipwreck

On 16 March 1801, she was lost in a shipwreck off the coast of Norfolk, England. She had been sailing from Yarmouth under the flag of Rear-Admiral Thomas Totty in an effort to reach the fleet of Admiral Sir Hyde Parker in the Sound preparing for the upcoming attack on the Danish fleet, with approximately 650 people on board. As the ship passed the Norfolk coast, she was caught in heavy wind and stuck on the Hammond Knoll Rock off Happisburgh, where she was pinned for some hours in the afternoon before breaking free but immediately being grounded on a sandbank, where the effect of wind and waves tore down the masts and began to break up the ship. She remained in that position for all of the following day, but late in the evening drifted off the sandbank and sank in deep water.

The admiral and 195 sailors escaped the wreck, either in one of the ship's boats or were picked up by a passing collier and fishing boat, but over 400 of their shipmates drowned in the disaster, most of them once the ship began to sink in deeper water.

The compulsory court martial investigating the incident, held on  in Sheerness, absolved the admiral and the captain (posthumously) of culpability in the disaster, posthumously blaming the harbour pilot and the ship's master, both of whom had been engaged to steer the ship through the reefs and shoals of the dangerous region, and should have known the location of Hammond Knoll, especially since it was daytime and in sight of land.

The remains of many of her crew were located by chance in a mass grave in Happisburgh churchyard during the digging of a new drainage channel. A memorial stone was erected in 1998 to their memory by the Ship's Company of the Royal Navy aircraft carrier HMS Invincible, and by the Happisburgh parochial church council.
