History / WWII - who really was the first to help Poland? [901]

Witam....
I'm really hoping this thread doesn't become an argument, and I wanna avoid that b/c i just wanna learn about this, but...about ww2 and Poland, who really was the first to help poland?

I've lived in the usa for 13 years, ever since i was 10 years old, so unfortunately I did not learn polish history, so only know from the schools here that mainly that USA's involvement in ww2 helped Poland. But then again from reading some posts on here, the Russians helped, but then someone replied that sure, they helped, right after killing a bunch of us...sooo, is this one of those answers that depends on who is telling it or is there really a straight answer as to who helped us? Is there a timeline of this?

It's really f*ing frustrating getting a straight answer. And it kinda pisses me off I dont know this. But, my family moved here when I was young so I only know so much. Its hard not to get a biased answer about issues of war and history.

So please I dont want this to turn into russian, american, whoever else bash-fest. I just want some sort of timeline, accurate facts as they happened, not what benefits a nation.

Dzieki...
