On 23 October 1805, French Captain Julien Cosmao made a sortie from Cadiz with some of the more seaworthy ships that had escaped the battle, in an attempt to retake some of the captured prizes.

A storm came up that wrecked many vessels and forced the remains of the French fleet back to Cadiz.

Argus left Cayenne on 15 March 1806, provisioned for a cruise of four months and in company with the French brig Observateur.

The governor of Martinique, Admiral Villaret Joyeuse, reportedly cashiered Argus's captain for his failure to capture Express.

The British report from the engagement states that Argus was armed with fourteen brass 8-pounder guns, which were the equivalent of English 9-pounders, and had a crew of 120 men.
