Napoleon's plan resembled earlier French attempts that culminated in the 1759 Battle of Quiberon Bay. Those schemes likewise sought to combine naval forces, cover transports bound for Britain and use a smaller expedition to Ireland as a diversion. The Trafalgar campaign was therefore another version of a recurring strategic problem rather than an entirely new solution. The comparison explains why British blockade and interception doctrine focused on preventing fleet concentration before an invasion force could move.

The Quiberon Bay precedent behind the invasion plan
The 1805 scheme repeated an older French pattern: combine fleets, shield troop transports and use an Irish expedition as a diversion.
