On April 15, 1940, M 1507 Teutonia played a role as a convoy escort in the Norwegian Campaign during World War II. The Norwegian Campaign was an essential operation, with convoys being a critical part due to the need to secure the movement of troops, equipment, and supplies.

The M 1507 Teutonia was a part of the Kriegsmarine's (the German Navy's) convoy escort group. Convoy escorts were tasked with protecting merchant ships and military transports from enemy submarines and surface ships. On this date, Teutonia, along with other escort vessels, likely undertook anti-submarine patrols and general protection duties to ensure the safe passage of the convoy through contested waters.

For more detailed and specific information about the operations on that day, naval logs or archives might provide further insights and records of the exact activities Teutonia was involved in.

If you are interested in learning more about the activities of M 1507 Teutonia or the broader operations of the Kriegsmarine during the Norwegian Campaign, I recommend consulting historical naval records or dedicated military history resources.
