As soon as the Military frontier region was established, Sombor became a military entrenchment, which meant that all the duties of soldiers towards the district stopped, which it fiercely opposed. In the entrenchment there were 200 soldiers, under the command of a captain, and they were divided into a cavalry and an infantry. The cavalry had two second lieutenants, two warrant officers, two sergeants and four corporals, with 90 privates. The infantry had one second lieutenant, one warrant officer, one sergeant, four corporals and 90 privates. If needed, the cavalry gave help to the settlements on the Tisza, and the infantrymen kept internal order, prevented plunders on the Danube, and together with the cavalry, made sure there were no bandits in the swamp area.

This document was a prerequisite, together with 150.000 forints in gold paid to the Court treasury, for granting Sombor the rank of Free and Royal City.
