It is said generally, that in 1939, Poland has been defeat by Germans by their superiority, etc.
But truth is such, that Polish Campaign would last any longer and could have other end, if not Soviet treacherous attack on Poland at 17th September 1939.
Exactly it has weigh on fates this campaign.
Poland must fight on two fronts and has lost back in East Poland.
In many places, battles with Soviets lasted to 2-3 October 1939(with Germans to 6 October 1939). They have incurred big losses(hide in reports), taking into account, that they combat with not numerous Polish troops - most often with reserve and spare units. Whole Polish divisions combat on German front.
For example: Soviets lost 42 tanks and about 60-80 armoured cars and 429 tanks that broke down - there are losses of armoured brigades ONLY.
But yet in each cavalry brigade and infantry division were organic tanks battalions. Their losses are unknown. But with certitude there was great than armoured brigades, for example: in battle of Szack, Poles have destroyed 10 - 12 tanks of 411th Tank Battalion from Soviet 52nd DS.
Interesting episode are fights with Soviets about Polish cities - Grodno, Wilno, Tarnopol...
It has come for encounters Polish tanks(Renault R 35 and Hotchkiss H 35) with Soviet armoured units.
Also it has come for German - Soviet fights...
