Shortly after his arrival, Schomberg was ordered to join the squadron of Captain Philip Beaver on the newly captured Mauritius.

When Beaver sailed for the Seychelles in March 1811, the command of the naval forces on the island devolved to Schomberg.

On 6 May 1811, a French squadron of frigates under the command of Commodore François Roquebert in Renommée approached Grand Port, not realizing that Isle de France (now Mauritius) had fallen to the British.

[2] On 14 May Astraea, Phoebe, Galatea, and Racehorse sailed from Port Louis for Tamatave, Madagascar and arrived on 20 May.

During the battle, Renommée and Clorinde badly battered Galatea, with the result that she lost 16 men killed and 46 wounded – the largest number of casualties of any vessel in the squadron.

Roquebert had sacrificed his flagship and ultimately his life to allow the frigates Clorinde and the badly damaged Néréide to escape.

In 1847 the Admiralty authorized the award of the Naval General Service Medal with clasp "Off Tamatave 20 May 1811" to all surviving claimants from the action.

In early 1814 Astrea was in company with Creole, which was under the command of Captain George Charles Mackenzie, who was Eveleigh's senior.

[5] Off the Cape Verde Islands they encountered two frigates and two merchant ships, one a brigantine and the other a schooner, all at anchor.

Two broadsides from Astrea then temporarily silenced the French frigate as fires aboard Creole took her out of the action for a while.
