Battle of Bautzen (1813)

• 1. Introduction

  ›

  The Battle of Bautzen, fought on the 20th and the 21st of May 1813, came down to a single question: could Napoleon finally destroy the Prusso-Russian army in the field? He had the numbers to do it. With 144,000 troops against a combined allied force of nearly 96,000, he held a commanding advantage. The allied generals, Gebhard Leberecht von Blücher leading the Prussians and Peter Wittgenstein commanding the Russians, had already been beaten at Lützen and were ordered to make a stand at Bautzen by Tsar Alexander I and King Frederick William III. They chose their ground carefully, anchoring their left on the town of Bautzen itself and their right on a chain of lakes, with two strong defensive lines stretching across the hills and villages east of the River Spree. Napoleon had a plan to use that defensive posture against them. The plan required Marshal Michel Ney. What happened when Ney arrived would haunt the French for the rest of the campaign.

• 2. Napoleon's Trap

  Napoleon's design for Bautzen was elegant in its logic. On the first day he would pin the allied army against its own defensive lines, preventing any escape, while Ney's forces marched to arrive the following day. Once Ney was in position behind the allied right flank, the Prusso-Russians would have nowhere to go. Napoleon expected a battle of annihilation. But faulty reconnaissance undermined his confidence before the fight even began. His intelligence suggested the allies held stronger positions and larger numbers than they actually did, and so Napoleon delayed setting his trap. Rather than pressing from the start, he decided to soften up the allied lines first, giving Ney's arrival even greater weight. That caution cost him time he could not recover.

• 3. Two Days of Battle

  Around noon on the 20th of May, Napoleon's grande batterie opened fire, and hours of fighting followed. The French overpowered the first allied defensive lines and seized the town of Bautzen itself. The Prusso-Russians fell back in good order. By nightfall the French were moving to cut the allies off from their retreat route, but the allied command had already learned that Ney was approaching their right flank. Marshal Ney, however, became confused. His faulty positioning left a gap, and the allies slipped through the night without catastrophe.

  Fighting resumed on the 21st of May. After several hours of setbacks, renewed French attacks began to gain momentum. The assaults were intended to fix the allies in place while Ney sealed the trap from behind. Ney grew distracted. He chose to seize a village along his route and lost sight of the strategic objective of cutting off the allied retreat. At 4:00pm, Tsar Alexander I recognized the threat Ney posed on the Russian right and concluded the battle was lost. He ordered a general retreat. Without Ney's forces closing the pocket, the Prusso-Russian army escaped the crushing encirclement Napoleon had designed.

• 4. A Pyrrhic French Victory

  ›

  Combined losses on both sides totaled around 20,000 at Bautzen. Some sources, including Dr. Stubner, argue the French suffered significantly more because their aggressive attack tactics repeatedly failed to cut off the allies. Those same sources put allied casualties at between 11,000 and 14,000. The imbalance matters: Napoleon held numerical superiority throughout and still could not deliver a knockout blow. The French victory at Bautzen is therefore often described as a Pyrrhic victory, a label that reflects the gap between what the numbers suggested was possible and what the battle actually produced.

  The personal cost went beyond the casualty count. General Geraud Duroc, Napoleon's close friend and Grand Marshal of the Palace, was mortally wounded by a cannonball the day after the battle and died. Duroc had been a fixture of Napoleon's inner circle, and his death added a private grief to a campaign already marked by strategic frustration.

• 5. The Truce and Its Consequences

  Following Bautzen, the allies requested an armistice on the 2nd of June 1813. Napoleon agreed. The Armistice of Pläswitz was signed on the 4th of June and was set to last until the 20th of July, though it was later extended to the 10th of August. Napoleon's aim was to use the nine-week pause to gather more troops, particularly cavalry, and to train the new forces he had been fielding. The allies, as it turned out, were not idle. They used the truce to mobilise better-prepared forces, and when hostilities resumed, Austria joined the coalition against France.

  Napoleon reportedly said later, during his exile on Saint Helena, that his agreement to that truce was a serious mistake. The pause benefited the allies far more than it benefited him. What had looked like a chance to regroup became the foundation for the broader alliance that would press France through the rest of 1813.
