The Irish Brigade of France fights at the Battle of Blenheim, a major battle of the War of the Spanish Succession, on August 13, 1704. The overwhelming Allied victory ensures the safety of Vienna from the Franco-Bavarian army, thus preventing the collapse of the Grand Alliance.
Louis XIV of France seeks to knock Leopold I, Holy Roman Emperor, out of the war by seizing Vienna, the Habsburg capital, and gain a favourable peace settlement. The dangers to Vienna are considerable as Maximilian II Emanuel, Elector of Bavaria and Marshal of France Ferdinand de Marsin‘s forces in Bavaria threaten from the west and Marshal Louis Joseph, Duke of Vendôme‘s large army in northern Italy poses a serious danger with a potential offensive through the Brenner Pass. Vienna is also under pressure from Francis II Rákóczi‘s Hungarian revolt from its eastern approaches. Realising the danger, the John Churchill, 1st Duke of Marlborough resolves to alleviate the peril to Vienna by marching his forces south from Bedburg and help maintain Emperor Leopold within the Grand Alliance.
A combination of deception and skilled administration, designed to conceal his true destination from friend and foe alike, enables Marlborough to march 250 miles unhindered from the Low Countries to the River Danube in five weeks. After securing Donauwörth on the Danube, Marlborough seeks to engage the Elector’s and Marsin’s army before Marshal Camille d’Hostun, duc de Tallard can bring reinforcements through the Black Forest. However, with the Franco-Bavarian commanders reluctant to fight until their numbers are deemed sufficient, the Duke enacts a policy of plundering in Bavaria designed to force the issue. The tactic proves unsuccessful, but when Tallard arrives to bolster the Elector’s army, and Prince Eugene of Savoy arrives with reinforcements for the Allies, the two armies finally meet on the banks of the Danube in and around the small village of Blindheim, from which the English “Blenheim” is derived.
Blenheim is one of the battles that alters the course of the war, which until then was leaning for Louis’ coalition, and ends French plans of knocking the Emperor out of the war. France suffers as many as 38,000 casualties including the commander-in-chief, Marshal Tallard, who is taken captive to England. Before the 1704 campaign ends, the Allies have taken Landau, and the towns of Trier and Traben-Trarbach on the Moselle in preparation for the following year’s campaign into France itself. The offensive never materialises as the Grand Alliance’s army has to depart the Moselle to defend Liège from a French counteroffensive. The war would rage on for another decade.
