It is probably the least heard story in the invasion of Poland, the counter offensive around the Bzura river. It brought temporary success to the Polish force, and they even push the Germans back to areas like Lowicz and Glowno. All in all I guess it doesn't matter, because from sept 9 - 19 1939, it was battle that they eventually lost. I will say this much about the Polish forces, they gave the Germans all they could handle for that short time.
