24.05.1944 registered letter from Zagreb to "Kroatische schnelle brigade" located in Lager Dollersheim in Reich today in Austria. "Kroatische schnelle brigade" or in Croatian "Brzi Zdrug" or "Fast Brigade" in English was formed on 01.04.1944 from 3 cavalry companies(konjanički sklop) and from 1st and 2nd bicycle battalion ( 1. i 2. koturaška bojna). On 21.12.1944 Brzi Zdrug was dismissed from Domobranstvo and become part of Ustaška vojnica. This Unit was to be equipped with motorised and armoured vehicles but this was only partially realised.
I havent found any reference of Brzi Zdrug training in Dollersheim with Kroatische Ausbildungs Brigade but this letter proves it.
