Following defeat at the Battle of Wagram, Archduke Charles retreated north into Bohemia hoping to regroup his battered forces. The French army had also suffered in the battle and did not give immediate pursuit. But two days after the battle, Napoleon ordered his troops north intending to defeat the Austrians once and for all. The French eventually caught up the Austrians at Znaim (now Znojmo, Czech Republic) on 10 July 1809. Realising they were in no position to give battle, the Austrians proposed a ceasefire as Archduke Charles went to begin peace negotiations with Napoleon. However, Marshal Auguste de Marmont refused to observe the ceasefire and committed his XI Corps of around 10,000 men into battle. With Marmont greatly outnumbered, André Masséna had no choice but to support him. By 11 July, Masséna's corps had joined Marmont's in battle but the Austrians had also reinforced their position around the town of Znaim. After two days of futile fighting, with both sides suffering similar casualties and neither side gaining any advantage, Napoleon finally arrived with news of an armistice and ordered Marmont to end the battle.
