London is presented as the destination of a possible appeal for assistance, not as the setting of a narrated scene. Its significance lies in the dilemma surrounding that appeal: George Krause needs help for an endangered escort force, but a transmission could tell the enemy how vulnerable the convoy has become.

London as a Destination for Help

With Viktor disabled and Cadena requiring protection, the convoy is nearly without an effective guard. Keeling must patrol around the two ships while preserving a sonar watch, and its fuel supply will soon become urgent. George Krause recognizes that he will have to appeal to London for help and break radio silence; the contemplated request connects the ships’ immediate predicament to the authorities who might provide support.

The Cost of Sending a Message

A transmission could expose more than the convoy’s position. German monitoring stations might infer from the call that the convoy was in serious trouble, encouraging submarines to concentrate against it. Silence, by contrast, would leave the enemy uncertain whether the convoy could still defend itself. London therefore represents necessary assistance, but reaching it by radio carries a tactical risk that could worsen the danger the appeal is meant to relieve.

Timing and the Expected Response

George Krause decides that the message should wait until about two in the morning, perhaps half past one. Sending it then would limit the remaining night in which submarines could organize an attack while leaving time for the Admiralty to arrange air cover at dawn. His estimate allows half an hour for the message to reach the highest authority, half an hour for orders to be issued, an hour for preparation, and two hours for the flight. The evidence describes a plan to contact London and an anticipated response, not confirmation that the message was sent or that assistance arrived.
