My map is a feature of the April Convoy Battle ONS-5. It began on April 28, 1943 (WWII), when Wolfsrudel Star and Amsel I attacked the convoy ONS-5.
Visualize it with a blue background and amazing graphics when I touch it up on Gimp and the Map Foundry workers construct it to perfection. Link to the original draft
