It’s fascinating living through a historical event and living to see how it gets reviewed much much later on. While I was not involved directly. My recollection only comes from news coverage at the time and through a movie.
The movie “Mrs Miniver” gives one a pretty good idea how the Brits rallied around that evacuation organizing every type of privately owned sea craft capable of channel crossing to provide crossing transport. Which most did several times. BTW Let’s not forget WWI and Paris taxies. So if you can and if available view it.
Because the bulk of Brit forces were brought back by these craft and because these were privately owned the French were evacuated mainly in Royal Navy troop transports there were some complaints . Which is where I was coming from when I mentioned the number of French (mostly army units) who were also evacuated. Since I haven’t viewed “Dunkirk” there were tons of equipment left but every attempt to disable that stuff was made. Don’t know it that aspect was covered in that flick
I’m not aware of Germans using a lot of captured British equipment later on. In the desert, they did use captured Matildas and Cruiser tanks, but those were local caputures, not what had shipped from the Continent.
The Germans did use a lot of captured French equipment, but they captured French equipment in vast quantities everywhere, not just at Dunkirk. Some of the French light artillery wound up on the Eastern Front as anti-tank guns issued to infantry units. The French had a large truck park, as their army was fully motorized. In the fall of 1941, most of those trucks burned out their transmissions in the mud between Smolensk and Moscow, and were left frozen in place.
Many of the French tanks, such as the H39s and Somuas, wound up as a “lend lease” program and went to equip the Hungarians. These tanks were no match for the T34/85 when the Soviets entered Hungary in late 1944.
