Very powerful. very good approach to a sad subject. It was moving and still informative. 5/5

I really liked this. It had a good flow that kept me comfortably reading, and a good idea that made me want to keep reading. I'm actually kind of confused here by:
"And with their guns, they made the choice
Of who was to live, or so to speak."

Do you mean that they killed them with guns? Or killed them on the 'inside'? I also don't think that mentioning Hitler's birthday as any kind of real impact on this poem. It seems kind of like additional words; a little out of place. But if it's based on a true story I guess it would be pretty good and it would have an effect on people who have heard about this.

"One of the plotters found a girl,
She hid like shy pray."
^This second line also seems kind of uncomfortable. As in it makes sense, it's a good idea however the wording makes it a little awkward. I think it has too little syllables. Otherwise, it was good. ^^
