The Siege of Philippsburg is conducted by French forces against forces in the fortress of Philippsburg in the Rhine River valley during the War of the Polish Succession.
The Duke of Berwick leads 100,000 men up the Rhine Valley in opposition to Austrian forces, of which 60,000 are detached to invest the fortress at Philippsburg, beginning on June 1, 1734.
A relief column of 35,000 under the aging Prince Eugene of Savoy (accompanied by Crown Prince Frederick of Prussia) is unsuccessful in actually relieving the siege.
On June 12, Berwick is killed by a cannonball while inspecting the trenches, and command of the besiegers falls to Marshals d'Asfeld and Noailles.
The fortress surrenders one month later, and the garrison withdraw to the fortress of Mainz with the honors of war.D'Asfeld is promoted to Marshal of France for his role in the campaign; Wuttgenau is promoted to lieutenant general for his spirited defense of the fortress.
