The discussion revisits the claim that German armour simply stopped outside Dunkirk. Royal Navy destroyers could bring 4.5- and 4.7-inch guns against land targets, weapons considerably larger than the tank guns being discussed. The Royal Air Force also contested the sky and prevented many attacking aircraft from reaching the evacuation area, even though some still got through. A German advance would therefore move under disputed airspace toward routes and targets accessible to naval fire. This combined threat is an operational factor rather than a complete account of the halt.

A side discussion combines Royal Navy destroyer gunfire with RAF air cover to explain why armour approaching Dunkirk would enter a dangerous joint-fire environment.
