The Battle of Cap de la Roque was a naval battle that took place on 22 May 1703 between a Dutch convoy protected by captain Roemer Vlack and a French squadron under Alain Emmanuel de Coëtlogon, during the War of the Spanish Succession. During this war the French and Spanish fleet could not face the English and Dutch in an open sea battle and therefore had switched to privateering. The allies were thus forced to protect their merchant convoys. Thanks to the sacrifice of Vlacq, the convoy got away intact, meaning this Dutch defeat had little impact on the cause of the Grand Alliance.
