In 1806, Lemaresquier commanded the 14-gun brig Teazer,[note 1] stationed at the entrance of the Gironde estuary at Le Verdon-sur-Mer.
On 15 July, at 1:30 in the morning, twelve boats from the British blockade slipped into the estuary and boarded the 16-gun César, anchored nearby, capturing her without a fight.
The squadron changed course to avoid the stronger British corvette, which focused her attention on Sylphe, the weakest of the three French ships.
Diligente was however prevented from pressing her advantage as Recruit's fire had left her hull in such a battered state that Lemaresquier had to order his gun crews to man the pumps to keep her afloat.
[4] James claims that Recruit kept fighting after her mast had fallen, and counter-attacked at 2 in the morning, forcing Diligente to flee;[5] Troude disputes this account.
He soon had reduced Rainbow to a battered state, but Avon resolutely came in support and put a 30-minute fight against the much stronger Néréide before herself retreating.
[6] On 3 February 1811, Lemaresquier departed Brest with a squadron under François Roquebert, bound for Île de France.
On the very day of their departure, an 18-day storm broke out, damaging the rigging of the frigates and breaking a gun port on Clorinde, through which she took in so much seawater that part of her food and gunpowder were flooded.
