In March, Tilly and the army of the Catholic League invaded from Bavaria; he was intercepted by Protestant forces under the Margrave of Baden-Durlach and Mansfeld, leading to the inconclusive Battle of Mingolsheim on 27 April. Mansfeld then moved onto Ladenburg, while the Margrave pursued the Bavarians; unaware Tilly had linked up with Córdoba, on 8 May, he was defeated at Wimpfen. Operations were then halted by disease.
