This was the first battle to be fought between the German and Russian armies on the Eastern Front during the Great War. As the Russians crossed the border into East Prussia General von Francois the commander of the German I Corps launched an unauthorised attack intended to drive the Russians back into Poland.
After some success and the capture of 3,000 prisoners, von Prittwitz (the commander of VIII Army) feared that Francois's corps could be encircled and ordered him to fall back on Gumbinnen.

Turn 1: both sides advance, while the German detached brigade (right) is recalled.
German artillery. Field guns on the left (with 2 gunnery points) and howitzers on the right.
Still in turn 3, the Russians concentrate 2 brigades against a single German brigade but roll appalling dice (low rolls are good). Meanwhile the Germans inflict a Rusian casualty.
Turn 4: The German detached brigade draws another club (no graduates of the staff college here!). The Russian main force launched an ill advised and costly assault on the German line. The Germans then roll round the Russian flank and their assault is shot in by all of the corps artillery. The Russians pass their first exhaustion test. Meanwhile the central Russian brigade has dug in.

The Germans are now able to concentrate against the exposed Russian flank.
Finally, as their line disintegrates the Russians fail their exhaustion test and pull back across the border.
