On the evening of 6 August 1807 the 'Hydra', 38 guns, Captain George Mundy, drove three armed French vessels into the Catalan port of Bagur, a narrow rocky harbour defended by a tower and a battery. The following day he anchored off the entrance and opened fire on the Spanish works. The fire was returned but the reply presently slackened and boats were sent in under Lieutenant Edward O'Brien Drury, in spite of a hail of bullets. The seamen landed and rushed the battery, which was evacuated by the enemy as the storming column pressed in. A detachment was left to garrison the battery while the rest of the landing-party, covered by fire from 'Hydra', hurried forward towards the town, entered it, drove out the enemy and secured the French vessels. A galling fire was, however, maintained by such crews as had fled ashore and taken post on the heights overlooking the harbour. Nevertheless, the enemy vessels were carried off and the party at the battery re-embarked. The British loss in this gallant enterprise was absurdly small. Only one man was killed and six wounded. For his brave and skillful conduct, Drury was promoted to be Commander.
