The Battle of Sievershausen occurred on 9 July 1553 in Sievershausen (today part of Lehrte in present-day Germany), between the Catholic Imperial troops and those of the Protestant Schmalkaldic League. 4,000 soldiers were killed, including Maurice, Elector of Saxony, the Protestant commander of the Catholic side. The Catholic retreat was covered by General Joachim von Röbel, who became famous as a result and ended his days as a field-marshal.
