His Majesty: "Well, Tirpitz, you've sunk a great many?"

Tirpitz: "Yes, sire, here is another U coming down."

On August 26, 1915, Squadron-Commander A. W. Bigsworth destroyed single-handed, a German submarine by bombs from his aeroplane off Ostend on the coast of Belgium.

The British Admiralty said in reference to this episode:

"It is not the practice of the Admiralty to publish statements regarding the losses of German submarines, important though they have been, in cases where the enemy have no other sources of information as to the time and place at which these losses have occurred. In the case referred to above, however, the brilliant feat of Squadron-Commander Bigsworth was performed in the immediate neighbourhood of the coast in occupation of the enemy, and the position of the sunken submarine has been located by a German destroyer."
