The battle of Rudolstadt was the decisive battle of the campaign. All eight corps took part in the battle, it was hard fought, both sides suffered similar casualties and the outcome was in doubt right to the end.
The battle opened with three corps per side, which filled the cramped battlefield. Then each side received a further corps after four moves. The Russian reserve arrived just in time to restore their right flank.
The fourth French corps had a long approach march to join the battle, and arrived too late to play a decisive part. By the time they were in position it was too late to commit them to attack. To do so would have resulted in heavy casualties, and night would fall before they could exploit any success.
At nightfall the Russians held the town, and the hills to the north. They had lost their left flank and two corps were in retreat. The French had no available reserve to continue the battle, and would require at least 24 hours to reorganise and redeploy before they could resume battle.
The Russians claimed a victory because they held the town, which was the objective of the battle.
