Why did the Pz. I perform adequately during the invasions of Poland and France?

The Pz. I performed adequately during the invasions of Poland and France primarily because it was deployed in massed formations as part of the German panzer divisions, rather than being used in isolation.1

These divisions utilized the doctrine of blitzkrieg, which emphasized speed, mobility, and the concentration of force at a specific point to paralyze enemy defenses. Furthermore, the Pz. I’s performance was bolstered by the fact that opposing forces during these early campaigns made poor use of their own antitank weapons.2341

While the Pz. I was lightly armed and protected, its role within a highly coordinated system of combined arms—supported by motorized artillery and dive-bombers—allowed it to contribute effectively to the rapid breakthroughs that defined these early German military successes.123
