The Battle of Grünberg was a military engagement between the forces of the Rotgeheiman Verteidigungsstaffel and the army of Porant that took place on 24 January 1913. While the small town was being assaulted by troops of the XIV VS-Panzerkorps, two concurrent engagements were being fought in Elssler and Neuhäusser, which were 10 km to the south-east and 18 km to the east, respectively. This town was one of three that was to be taken before Rotgeheiman troops could advance further. The engagement lasted from around 7:00 a.m. to 9:45 a.m.

Background

Rotgeheiman Preparations

Following the capture of Widerhausen on 22 January, the troops of the XIV VS-Panzerkorps, XII VS-Panzerkorps, and II VS-Panzerkorps were required to seize the next three objectives. The small towns of Grünberg, Elssler, and Neuhäusser were the objectives to be taken. The XII VS-Panzerkorps was assigned to attack Neuhäusser, and the II VS-Panzerkorps to attack Elssler, leaving Grünberg to be taken by the XIV VS-Panzerkorps. The capture of the three key towns would form a semi-circle around the Porantan beachhead, entrapping their land forces and preventing any further incursions by Porantan forces deeper into Hundermenschen.

Porantan Preparations

Grünberg was an essential front line defense post since the loss of Widerhausen. The town itself had been fortified with a small network of trenches running around the city, and most streets had makeshift barricades blocking access. A full Porantan infantry regiment was assigned to the defense of the town, but retreating Porantan troops from other battlegrounds meant that a little over a full regiment was present. Also taking part in the defense were three fighter planes that managed to evacuate from Widerhausen and around 20 tanks of various Porantan armored units. Porantan units fortified themselves and were reported by all field commanders as fully ready by evening of 21 January.
