Relief of Konstanz (1633)

The Relief of Konstanz in 1633 was a battle of the Thirty Years' War. A combined force of Spain and the Holy Roman Empire lifted the siege of Konstanz, that was besieged by the Swedish and their German allies.

Out of fear of an approaching Spanish army under the Duke of Feria, Gustaf Horn attempted to close the Spanish road into south-west Germany. He tried to capture imperial city of Konstanz, part of Habsburg Further Austria, in order to block the exit from the Tirolean passes through the Alpes. Horn hoped to encourage the Swiss to join the Swedish alliance against their common enemy, the Austrian Habsburgs.
