, and became stuck in weather that was 'not at all tempestuous.' A boat was sent back to the shore the following morning for help, and whilst the crew waited for it to return, another ship from the Nore arrived to offer assistance, having heard Colchester's cannons being fired in a signal of distress. The would-be rescuer was however kept from the stricken ship by the wind.

In the afternoon of Monday 22 October, the fore and mizzen masts were cut away in an effort to prevent the ship working herself to pieces. This was deemed insufficient, for Captain Cornwall had the ship scuttled

; on Tuesday morning lots were drawn to decide who could use the ship's longboat to get to safety. In spite of this, the ship's surgeon and 30 others took the longboat whilst the crew were drawing their lots; the boat subsequently sank, drowning 13. Four others who had jumped for the boat but missed were also drowned.

The boat Colchester had sent away in the morning of 22 October returned with six fishing vessels on 23 October, but they were unable to come to the ship's aid until the following morning when the sea, which had worked up a little overnight, had calmed again. The captain and 365 men were saved; approximately 40 men and one lieutenant were lost in total.
