An Ultra decrypt (KO 316 of 13 April) mentions that on 5 and 6 April Renault and Wolff tanks were ordered to come under command of 8. Flak-Division and report to Flak-Regiment 122(E) at Walsrode. ‘Wolff’ tanks are a mystery to me. As the Wolff munitions plant was at Bomlitz near Walsrode it is possible that in some way the decrypt confused the plant with a type of tank. Alternatively, as Harland and Wolff manufactured Matildas, Churchills and Centaurs it could be that they were captured British tanks. British accounts make reference to the ancient French tanks but no mention of 'Wolff' tanks. Any ideas?
The Germans mounted Flak on Wolff trucks and may also have done so on Renault. Renaults were certainly used to tow German AA guns
