Admiral Nelson failed at Boulogne-sur-Mer

The English Admiral Nelson suffered a memorable failure in August 1801 against the French fleet gathered at Boulogne-sur-Mer. The French ships, cleverly arranged in a quincunx, repelled the enemy assaults and inflicted the loss of 200 men on the British. This defeat discouraged London and led directly to the signing of the Treaty of Amiens on March 25, 1802.
