LOCUST was blown back into the Downs again on 5 April.
- On 8 December 1804 LOCUST covered an attack by the SUSANNAH, an explosion vessel, commanded by Lieut. STEWART of MONARCH, on a pile fort, Fort Rouge, off Calais.
At the same time Capt. BROWNRIGG of DART, and Lieut. BARTHOLEMEW of ANTELOPE, made an unsuccessful attempt to place two carcasses (a 'torpedo' consisting of a barrel of gunpowder with a clockwork firing mechanism) against the fort.
LOCUST kept close in to draw the fire from the shore.
- On Friday 8 March 1805 LOCUST was ordered by Capt. OWEN of IMMORTALITE to run in under the Ambleteuse batteries to engage a number of small French vessels.
Lieut. LAKE was in the act of lowering his jolly boat to take possession of an enemy cutter which had struck when LOCUST was hit by a 42 lb shot which sent the foremast overboard.
The Frenchman re-hoisted his colours and made for the shore.
LOCUST was towed into Deal by PINCHER, almost a complete wreck, and was then sent round to Sheerness for repair.
LOCUST suffered no casualties although she was subject to the fire of eleven batteries and a number of field pieces at pistol-shot range.
