The Battle of Oudenarde, also known as the Battle of Oudenaarde, was a major engagement of the War of the Spanish Succession, pitting an Anglo-Dutch force consisting of eighty thousand men under the command of the Duke of Marlborough, Lord Overkirk and Prince Eugene of Savoy against a French force of eighty-five thousand men under the command of the Duc de Bourgogne and the Duc de Vendôme, the battle resulting in a great victory for the Grand Alliance. The battle was fought near the city of Oudenaarde, at the time part of the Spanish Netherlands, on 11 July 1708. With this victory, the Grand Alliance ensured the fall of various French territories, giving them a significant strategic and tactical advantage during this stage of the war. The battle was fought in the later years of the war, a conflict that had come about as a result of English, Dutch and Habsburg apprehension at the possibility of a Bourbon succeeding the deceased King of Spain, Charles II, and combining their two nations and empires into one.Lynn: The Wars of Louis XIV 1667–1714
The engagement itself came about after a series of offensive and defensive manoeuvres between an Allied army under the command of Marlborough and a French army under the command of the Duc de Bourgogne. The two French commanders quarrelled about the direction their army should take, although roughly a month before the battle, the French army moved westwards and captured the Allied-held fortresses of Bruges and Ghent. This proved to be an unexpected and worrying action to Marlborough, who waited until Eugene had joined his army before he decided to undertake any offensive operations. The French moved to attack again, aiming to capture the city of Oudenaarde, which would cut off communication and supply routes between Marlborough and England and thus allow for a significant victory over the Grand Alliance. Marlborough managed to figure out the French plan of action, and forced marched his men towards Oudenaarde to defend it from the expected French attack. On 11 July, the two forces met near the city.
During the engagement, Allied cavalry moved to engage the French forward positions, killing or capturing many soldiers and pushing them back. For unknown reasons, a significant portion of the French army kept in reserve was never ordered to move up and engage, thus leading to a significantly weakened force facing the Allies. The infantry battalions on both sides moved to engage each other, with skilled deployment of cavalry by Cadogan ensuring the rout of many of the French infantry battalions, weakening their positions. Both sides settled into an engagement on opposing sides of the river, with several further mostly fruitless cavalry charges attempted by both sides. Marlborough initiated a flanking manoeuvre, gaining the allies a significant tactical and strategic advantage. Faced with mounting casualties, the French commanders made the decision to withdraw from the field. The battle was the third major victory that Marlborough had obtained during the war, boosting his military renown alongside that of Eugene, whose tactical contributions were vital to this victory.
Background
The War of the Spanish Succession, fought from 1701 to 1714, was a European conflict in the early 18th century, triggered by the death of the childless Charles II of Spain in November 1700, the last Habsburg monarch of Spain. His closest heirs were members of the Austrian Habsburg and French Bourbon families; acquisition of an undivided Spanish Empire by either threatened the European balance of power and thus the other leading powers became involved. Charles bequeathed an undivided monarchy of Spain to his grandnephew Philip, who was a grandson of Louis XIV of France. Philip was proclaimed King of Spain on 16 November 1700. Disputes over territorial and commercial rights led to war in 1701 between the Bourbons of France and Spain and the Grand Alliance, whose candidate was Charles, younger son of Leopold I, Holy Roman Emperor. The primary opponents of the Bourbon succession were the Kingdom of England (later the Kingdom of Great Britain after the Acts of Union with Scotland), the Holy Roman Empire and the Dutch Republic. In addition, many Spaniards opposed the idea of a Bourbon ruling Spain, and threw their lot in with Charles. Initially, the war went favourably for the French, given their vast army and navy and extremely advantageous geopolitical position. However, crushing defeats at Blenheim and Ramillies caused the war to settle into a stalemate, as the forces of the Grand Alliance could not advance into French territory, nor could the French advance into Habsburg territories either.
As the French army moved closer to the border with the Spanish Netherlands in 1708, the two French commanders began quarrelling over which battle plan they should adopt. Vendôme wished to attack the city of Huy, which could draw Marlborough in pursuit of his forces and weaken the overall allied position. The eventual plan adopted, however (under direct orders from Louis XIV), was to attack Flanders. The French army moved eastward, until they reached the city of Braine-l'Alleud, which was about twenty-five kilometres south of Brussels, and allowed the French to threaten the nearby city of Leuven. Marlborough moved his forces to a few miles south of Leuven, in order to sufficiently protect both cities from a potential French assault. The French army then remained inactive for more than a month, not making any major movements whatsoever. This allowed the much-delayed Eugène to bring his forces across the Rhine and head towards Marlboroughs position. On 5 July, however, the French unexpectedly moved westward, quickly capturing the cities of Bruges and Ghent (although about three hundred British soldiers held out in Ghent for a few days). This unexpected move both demoralised and confounded Marlborough and his army, and he did not make any offensive moves until Eugène along with his army arrived to join him. The French army had control over the entire length of the Scheldt from the French border to the newly taken city of Ghent.
Only one Allied fortress remained: the city of Oudenaarde. If the French managed to capture that city, Marlborough's army would be cut off from the coast, causing them to lose communication with England. Marlborough managed to guess the French battle plan, and also correctly guessed the method by which the French army would attempt to take Oudenarde—they would march down the east bank of the Scheldt (closer to Marlborough's troops), while leaving a large covering force between the two opposing armies. The French army set out on 8 July, marching toward the city of Lessines. However, Marlborough made one of the most impressive forced marches in history, capturing the city on 10 July. This forced the French commanders to attempt to simply to wade across the Scheldt and take Oudenaarde from that position. Marlborough again ordered a forced march of his troops. This time, though, he ordered eleven thousand troops to hold the main crossing point across the Scheldt, under the command of his Quartermaster General, William Cadogan. Cadogan's force built five additional pontoon bridges to allow Marlborough to get his eighty-thousand-strong army across the river, until French foragers discovered the allied presence around 9:00 a.m., initiating the battle.
Battle
Cadogan, a British cavalry commander, ordered some dragoons under the command of Danish general Jørgen Rantzau to capture men from the French advance guard. Many of those troops managed to escape and alerted Lieutenant General Charles-Armand de Gontaut, duc de Biron, who commanded the French vanguard to the presence of Allied troops on the west bank. When de Biron advanced, he was disagreeably surprised by the large number of Allied cavalry already across the river, along with the approaching Allied infantry. Although he was ordered to attack by Vendôme, he hesitated upon seeing the reinforced line of twenty infantry battalions (including the four that had been left to guard the pontoon bridges). Biron's own forces comprised only seven infantry battalions and twenty cavalry squadrons. He had been given reliable advice that cavalry could not negotiate the marshy terrain in the area and decided not to attempt a crossing. At this time, Eugene, along with twenty squadrons of Prussian cavalry, moved across the river and occupied crucial positions. While Biron's troops were manoeuvring, the leading British infantry brigade had arrived, under the command of John Campbell, 2nd Duke of Argyll. Cadogan, given authority from Marlborough, attacked Biron's seven infantry battalions of Swiss mercenaries with his division (consisting mainly of cavalry). The isolated Swiss mercenaries were immediately pushed back and the Allied force destroyed Biron's units, until they reached a large mass of French cavalry, at which point they were forced to retire, outnumbered. The force which performed this action was Rantzau's cavalry, with the future King George II among them.Henderson: Prince Eugen of Savoy, p. 162
Burgundy, making another mistake, decided to launch an attack, over protests by Vendôme. The French right wing began to attack the Allied positions near Eine, while the left wing, for unknown reasons, remained stationary near Huise. A very strong position was held by the Allied left wing. Twenty-eight cavalry squadrons protected the right flank of Cadogan's infantry, which would receive the attack, which proceeded at about 4:00 p.m.. Burgundy ordered the assault, which landed on Prussian cavalry squadrons under Dubislav Gneomar von Natzmer. Although intense fighting ensued, the attack was dispersed. Then, Vendôme made a dubious tactical decision to personally lead an attack of twelve infantry regiments, fighting hand-to-hand with a half-pike. This meant that while one commander (Burgundy) was in his headquarters with no view of the ongoing battle, the other commander was personally fighting in the field, with no possibility of directing his men. Most historians agree that had the French left wing attacked the weakened Allied right wing, it would have been forced to retreat. Vendôme realized this, asking Burgundy for permission to attack with the left wing. Burgundy sent back a messenger with a message of refusal but the messenger failed to deliver the message. The situation worsened with Vendôme believing that support would arrive for his troops, who were lengthening their line of battle and threatening to envelop the Allied left flank. As French infantry regiments approached, they lengthened the Allied line but too slowly and not great enough in extent to prevent the French from threatening the Allied positions.
Around the same time, the Dutch field deputies Sicco van Goslinga and Adolf Hendrik van Rechteren moved near where Marlborough was leading the army. They perceived him to be unsteady and indecisive, possibly as a result of accidentally falling into a deep ditch with his horse on the night of 10 July. Concerned over what they saw, Goslinga and Van Rechteren requested Eugene, who had so far remained in the background, to intervene and assume supreme command of the Allied army. Following some urging, as he was not in either British or Dutch service, Eugene gave in and stated: "Well now gentlemen... I will do what you ask of me."
