Battle of Nebelheim

The Battle of Nebelheim is often held up as an example of a true pitched battle, by scholars of the Empire.

To this battle the army of the Empire, led by Konrad, Elector Count of Ostland, engaged a large horde Orcs, led by Warlord Gorkfang. Knowing that the Orcs would press on regardless of losses and seek to overwhelm the Empire army by force of numbers alone, Konrad chose his ground carefully and devised a cunning plan. Then he deployed his army in the path of the invading Orc horde, forming up his carefully considered battle line in open, rolling terrain that formed a natural arena for the battle. Konrad then deliberately positioned thin lines of missle troops in the centre and big blocks of solid troops on the flanks.

The Orcs approached and seeing the apparently thin and weak centre, went into a headlong and ill-considered advance. Of course Konrad's centre gave way and the Orcs surged onward oblivious to the approaching doom. It was now time for Konrad, relying on the immense discipline of his men, to close the trap. The massive and resistant Empire formations on both flanks, swung inwards and hammered the Orc army from both sides. It is said that the Orcs were jammed together so closely in the melee that they were unable to use their weapons and so fell readily and in great heaps to the massed halberds of teh Ostlanders. Gorkfang, himself fell, and his horde was annihilated. It was a famous victory.
