A four-frigate squadron near the Scheldt provided invasion warning and coastal surveillance. The river was an obvious departure route for a force aimed at Britain. From the masthead, the squadron could observe three French frigates and a newly launched Dutch 64-gun ship at anchor. The ships patrolled the Dutch and Belgian coasts through August and the first half of September. Riou continued exercising Amazon's gunnery teams throughout the watch, linking reconnaissance duty with sustained combat readiness.
