Painting by Gilbert
The Action of 21 April 1806. In the foreground, HMS Tremendous aborts her attempt at raking Cannonière under the threat of being outmanoeuvered and raked herself by her more agile opponent. In the background, the Indiaman Charlton fires her parting broadside at Cannonière. The two events were in fact separated by several hours.
