The Patrol Zone

The following joint Anglo-American statement on submarine and anti­submarine operations is issued under the authority of the President and the Prime Minister:

“During May our shipping losses have been by far the lowest for any month of the war, and they have in fact been a fraction of the losses inflicted on enemy shipping by our warships and aircraft, although their merchant shipping is petty compared to that of the Allies.

“There has been a lull in the operations of the U-boats which perhaps indicates preparation for a renewed offensive. The change which had come over the scene is illustrated by the fact that in spite of the few U-boats at sea, several are now sent to the bottom for each merchant ship sunk whereas formerly each U-boat accounted for a considerable number of merchant ships before being destroyed.

“This is to be ascribed to the vigilance and to the relentless attacks of our Anglo-American-Canadian and other anti-U-boat forces, including the scientists who support them in a brilliant manner.”
