Well I feel like a dunderbunny

So I started a new campaign yet I set it in late 39 with the 2nd(?) flotilla, and I get my first contact while Im traveling under water, I go on surface and meet her course perpendicular, I set up, aim and fire. It was night and I watched as a magnetic torpedo explodes right under her and is going to for sure sink her. Then as I look closer in free cam, I notice a german flag I hope it doesnt sink
