Virtually every French weapon from 25mm upward penetrated the 7-13mm of the Panzer I. Although the Panzer II fared somewhat better, especially those that had been up-armoured since the Polish Campaign, their losses were high.
Næsten alle franske våben fra 25 mm og op gennembrød 7-13 mm-panseret på Panzer I. Selv om Panzer II klarede sig noget bedre, især de som var blevet opgraderet efter felttoget i Polen, var deres tab store.
