my jaw is still dropping when someone is writing that the Germans were by 15 september stalemated by Poles and Poles launched offensives

(how much)with 250000 men (why not 500000 ?) and fought battles larger and more hard fought then the entire Ardennes campaign,while "forgetting" that on the first days,Poland was begging,asking,demanding Allied support.Is this not a contradiction,Poland beying able to do the job on its own(no need for allied support?)
Of course;I am only a moron
