of attack by sea, air and land artillery, as the Germans approached the Straits of Dover. The plan was termed Operation Fuller. It was not executed well, principally because the Germans vessels were not detected until they were almost at Dover. Consequently, everything was hurried and poorly coordinated. Esmonde’s squadron received orders to attack, but no fighter coverage materialised. He waited as long as he felt he could for his escorts to appear, but eventually took off without them. One of the fighter squadrons (10 Supermarine Spitfires of No. 72 Squadron RAF) did rendezvous with Esmonde's squadron; the two squadrons were later attacked by enemy fighters of JG 2 and JG 26 as part of Operation Donnerkeil, the German air superiority plan for the mission. The subsequent fighting left all of the planes in Esmonde's squadron damaged, and caused them to become separated from their fighter escort. The torpedo bombers continued their attack, in spite of their damage and lack of fighter protection. There was heavy anti-aircraft fire from the German ships, and Esmonde's aeroplane possibly sustained a direct hit from anti-aircraft fire that destroyed most of one of the port wings of his Swordfish biplane. Esmonde led his flight through a screen of the enemy destroyers and other small vessels protecting the battleships. He was still 2,700 metres from his target when he was hit by a Focke-Wulf Fw 190, resulting in his aircraft bursting into flames and crashing into the sea. The remaining aircraft continued the attack, but all were shot down by enemy fighters; only five of the 18 crew survived the action. The four surviving officers received the Distinguished Service Order, and the enlisted survivor was awarded the Conspicuous Gallantry Medal. The courage of the Swordfish crews was noted by friend and foe alike. Admiral Bertram Ramsay later wrote, "In my opinion the gallant sortie of these six Swordfish aircraft constitutes one of the finest exhibitions of self-sacrifice and devotion to duty the war had ever witnessed", while Admiral Otto Ciliax in the Scharnhorst described "The mothball attack of a handful of ancient planes, piloted by men whose bravery surpasses any other action by either side that day". As he watched the smoking wrecks of the Swordfish falling into the sea, Captain Hoffmann of the Scharnhorst exclaimed, "Poor fellows, they are so very slow, it is nothing but suicide for them to fly against these big
