Cologne War: Forces under Ernest of Bavaria defeated Gebhard Truchsess von Waldburg's troops at the siege of Godesberg.

The Cologne War was a conflict between Protestant and Catholic factions that devastated the Electorate of Cologne, a historical ecclesiastical principality of the Holy Roman Empire, within present-day North Rhine-Westphalia, in Germany. The war occurred within the context of the Protestant Reformation in Germany and the subsequent Counter-Reformation, and concurrently with the Dutch Revolt and the French Wars of Religion.
