The map of the 2nd edition of "Magyar Atlas" shows the Brod Regiment, which together with Gradiška and Petrovaradin Regiment formed the Slavonic Military Frontier, which was not only a tactical but also a territorial and administrative unit. The Brod Regiment was located north of the Sava River, somewhat west of Slavonski Brod to a little east of Vinkovci, with which it is not connected by road. The Military Frontier was abolished in 1873 and incorporated in Croatia-Slavonia in 1881. The map shows the relief, i.e. the plains and the local wetlands, the road to Osijek and many toponyms.
