1940s WWII

Me and some of my comrades were sent on patrol in enemy territory, it was a forest, but it was daytime and light

Walking through this forest, I see a young girl in a military uniform hiding behind a tree and looking towards the road; I didn't know who she was because she was acting strange; after a few seconds I crept up on her unnoticed and turned her around to face me, pinned her against the tree, putting my gun to her throat

James "Who are you and what are you doing here?"

I was more alert and serious than ever
