In Port After Successful Patrol Duties
An aerial photograph of a British submarine under way, with an inset of a Beaufort torpedo-bomber, carries a caption saying the planes 'are the terror of Nazi shipping' and that one squadron destroyed over 103,000 tons of shipping. The tell for card-stacking is a single tonnage total with no source, period or losses; the tell for name-calling is the loaded label 'terror of Nazi shipping'.

Text on the object
E B.4 [logo: Union Jack] FOR FREEDOM IN PORT AFTER SUCCESSFUL PATROL DUTIES A BRITISH SUBMARINE arrives safely back in port after a patrol. The submarine's weapon is the torpedo. Inset above the submarine is another kind of British torpedo-carrier—a Beaufort torpedo-bomber. These planes are the terror of Nazi shipping. One Royal Air Force squadron has destroyed over 103,000 tons of enemy shipping since it was equipped with Beaufort bombers. Above the water and under the water alike, the striking power of Britain at sea grows greater every day.
