1st week of October, 1939
U-37 and U-38 are stationed off the North American North Seaboard. A small convoy of four freighters escorted by HMS Jervis and HMS Valorous is sandwiched between the two submarines.

The challenge is the British destroyers are closing on U-37 head on. So the German subs stagger their attacks. U-38 fires first, killing a merchantman with a pair of torpedoes while U-37 closes the distance to her chosen target.

Before long, a pair of cargo ships are going down, and U-37 has retreated to safety. Yet the British were fast to come about and they're actively pinging the waters surrounding U-38 with their SONAR.

The U-boat dives as deep as her hull will allow and tries to slip away. There are some tense moments...and a single depth charge attack by Jervis....but the weather is poor, the sub is running deep, and eventually she makes good on her escape.
Tally so far: 138,000 tons and two destroyers.
