French losses were immense, with over 27,000 killed, wounded and captured.
Moreover, the myth of French invincibility had been destroyed and Louis's hopes of an early and victorious peace had been wrenched from his grasp.
Mérode-Westerloo summarised the case against Tallard's army: "The French lost this battle for a wide variety of reasons.
For one thing they had too good an opinion of their own ability ... Another point was their faulty field dispositions, and in addition there was rampant indiscipline and inexperience displayed ... It took all these faults to lose so celebrated a battle."
It was a hard-fought contest, leading Prince Eugene to observe – "I have not a squadron or battalion which did not charge four times at least."

Although the war dragged on for years, the Battle of Blenheim was probably its most decisive victory; Marlborough and Eugene, working indivisibly together, had saved the Habsburg Empire and thereby preserved the Grand Alliance from collapse.
Munich, Augsburg, Ingolstadt, Ulm and all remaining territory of Bavaria soon fell to the Allies.
By the Treaty of Ilbersheim, signed 7 November 1704, Bavaria was placed under Austrian military rule, allowing the Habsburgs to use its resources for the rest of the conflict.

The remnants of the Elector of Bavaria's and Marshal Marsin's wing limped back to Strasbourg, losing another 7,000 men through desertion.
Despite being offered the chance to remain as ruler of Bavaria (under strict terms of an alliance with Austria), the Elector left his country and family in order to continue the war against the Allies from the Spanish Netherlands where he still held the post of governor-general.
Their commander-in-chief that day, Marshal Tallard  – who, unlike his subordinates, had not been ransomed or exchanged – was taken to England and imprisoned in Nottingham until his release in 1711.

The 1704 campaign lasted considerably longer than usual as the Allies sought to wring out maximum advantage.
Realising that France was too powerful to be forced to make peace by a single victory, however, Eugene, Marlborough and Baden met to plan their next moves.
For the following year the Duke proposed a campaign along the valley of the River Moselle to carry the war deep into France.
This required the capture of the major fortress of Landau which guarded the Rhine, and the towns of Trier and Trarbach on the Moselle itself.
Trier was taken on 27 October and Landau fell on 23 November to the Margrave of Baden and Prince Eugene; with the fall of Trarbach on 20 December, the campaign season for 1704 came to an end.

Marlborough returned to England on 14 December (O.S) to the acclamation of Queen Anne and the country.
In the first days of January the 110 cavalry standards and the 128 infantry colours that were taken during the battle were borne in procession to Westminster Hall.
In February 1705, Queen Anne, who had made Marlborough a Duke in 1702, granted him the Park of Woodstock and promised a sum of £240,000 to build a suitable house as a gift from a grateful crown in recognition of his victory – a victory which British historian Sir Edward Shepherd Creasy considered one of the pivotal battles in history, writing – "Had it not been for Blenheim, all Europe might at this day suffer under the effect of French conquests resembling those of Alexander in extent and those of the Romans in durability."
However, military historian John A. Lynn consider this claim unjustified as Louis XIV never laboured such objective, as the campaign in Bavaria was intended to bring only a favourable peace settlement and not domination over Europe.

The famous Lake poet Robert Southey scathingly criticised the Battle of Blenheim in his anti war poem After Blenheim.
However Robert Southey himself is said to have later praised the victory.
The poem points out the complacency of the public and lack of curiosity.
