The action of 28 February 1799 was a minor naval engagement of the French Revolutionary Wars, fought off the mouth of the Hooghly River in the Bay of Bengal between the French frigate Forte and the Royal Navy frigate HMS Sybille. Forte was an exceptionally large and powerful ship engaged on a commerce raiding operation against British merchant shipping off the port of Calcutta in British India. To eliminate this threat, Sybille was sent from Madras in pursuit. Acting on information from released prisoners, Edward Cooke, captain of Sybille, was sailing off Balasore when distant gunfire alerted him to the presence of Forte on the evening of 28 February. The French frigate was discovered at anchor in the sandbanks at the mouth of the Hooghly with two recently captured British merchant ships.

Sibylle was a 38-gun Hébé-class frigate of the French Navy. She was launched in 1791 at the dockyards in Toulon and placed in service in 1792. After the 50-gun fourth rate HMS Romney captured her in 1794, the British took her into service as HMS Sybille. She served in the Royal Navy until disposed of in 1833. While in British service, Sybille participated in three notable single-ship actions, in each case capturing a French vessel. On anti-slavery duties off West Africa from July 1827 to June 1830, Sybille captured many slavers and freed some 3,500 slaves. She was finally sold in 1833 in Portsmouth.
