Account of the Battle of Dettingen:
The Battle of Dettingen is a significant victory for the British Army, being the only time in modern history that a British Force has been led into battle by a reigning monarch, King George II.

Although ostensibly fighting to preserve Flanders from the predations of Louis XV’s French armies, the British army’s presence on the Continent from 1742 was as much to preserve the independence of Hanover, King George II being Elector of Hanover. The British force constituted part of what was known as the “Pragmatic Army”, comprising British, Austrian and Hanoverian troops.

In early 1743 the Pragmatic Allies were at a loss how to use their army against the French. Finally, late in the campaigning season and at King George II’s insistence, the Pragmatic Army march south to Frankfurt am Main and occupied the area to the west of Mainz on the River Main. King George II intended that the army’s presence should influence the election of the new Archbishop of Mainz, an elector in the Holy Roman Empire and therefore of importance in the affairs of Hanover.

The Pragmatic Army marched from Flanders during May 1743 and encamped near Aschaffenburg, around the village of Klein Ostheim. A large French Army under the Duc de Noailles occupied the south bank of the River Main to the west.

The Pragmatic generals were the Earl of Stair, in nominal overall command, the Duke D’Ahrenburg and Marshall Neipperg commanding the Austrians and General Ilton commanding the Hanoverian contingent.

On 8th June 1743, King George II, the King of England, joined the army, amid a flurry of celebrations and salutes. He brought with him a considerable retinue, conveyed by a long column of carriages and some 600 horses that paralysed the local roads for days, and his younger and favourite son, William Augustus, Duke of Cumberland, a major general in the British Army. Over the next few days George attended church services and functions in Mainz in anticipation of the election of the new archbishop.

The situation of the Pragmatic Army deteriorated dramatically when the French cut the route along the Rhine and Main Rivers by which the army received supplies from its Flanders base. There had been no proper supply of bread for a week, when finally on 16th June 1743 King George II ordered the retreat to begin; west along the road to Hanau and Frankfurt and then north to Flanders.

The Pragmatic Army’s route lay along the north bank of the Main River. Within three miles, King George II’s army would pass through the village of Dettingen, where the road crossed several marshy brooks flowing into the Main.

As the Pragmatic Army marched towards Dettingen, advanced parties reported that the French occupied the village, blocking the road. During the night, the French, commanded by the Duc de Grammont, had crossed the river, using bridges of boats across the Main and held the village and the marshy ground between Dettingen and the hills in strength.

The presence of the French took the Pragmatic Army by surprise. It is a surprise that such a large force could have been in ignorance of the presence of the enemy on its own side of the river within five miles of its camp.

Preparing to give battle, the British, Austrian and Hanoverian troops formed line; the Main River on the left and the wooded Spessart Hills on the right. The Pragmatic Army took from 9am to midday to form up. This length of time must have been due to the lack of co-ordinated training between the regiments and national contingents and the difficulty of moving from a column of march with a considerable quantity of baggage into battle line.

No doubt there was great anxiety at the predicament in which the Pragmatic Army found itself.

The Duc de Noailles’ plan was, while the Duc de Grammont held the line of Dettingen and the streams preventing the Pragmatic allies from continuing their march, to hurry a section of his army along the south bank of the Main and cross at Aschaffenburg in the Pragmatic Army’s rear. The Pragmatic Allies would be caught between the two French forces and perhaps forced to surrender; King George II becoming a French prisoner.

As the British regiments formed to face the French in Dettingen, they watched Noailles’ troops on the far bank marching east towards Aschaffenburg. After a hurried consultation the Pragmatic commanders dispatched the British and Hanoverian Foot Guards in haste back towards Aschaffenburg.

The French batteries on the south bank of the Main River began the battle, opening fire across the river as the marching French troops cleared their front. The bombardment was directed at the British cavalry moving along the North bank.  The French fire seems to have inflicted few casualties.

It is said that de Grammont’s clear orders were to stay in Dettingen and force the Pragmatic Army to attack him. If this is so he disobeyed. As the British, Hanoverian and Austrian regiments completed their line the French advanced out of Dettingen to the attack.

There is little reliable information on the form of the battle or on the formation adopted by the Pragmatic troops. It would appear that British regiments were in the front line, but in what order is not clear. At an early stage, French cavalry, the Maison du Roi, charged the British cavalry by the river. The French were driven back, apparently with significant loss.

The French assault bore all the hallmarks of extreme confusion, possibly a spontaneous and undisciplined advance that De Grammont did not order. The cavalry charge was followed by a French infantry attack on the Pragmatic line of foot, the French appearing to come out of Dettingen pell-mell and in some disorder.

The French foot were repelled and, panic stricken, hurried back through Dettingen, re-crossing the Main by the bridges of boats. One of the bridges collapsed and many French troops are reputed to have been drowned.

Royal Welch Fuziliers: Battle of Dettingen

No attempt seems to have been made to follow up the repulse of De Grammont’s force. In due course the Pragmatic Army resumed its march and continued its way to Hanau, passing within a half mile or so of the chaos at the French bridges of boats.

The British Army had not been in a major continental war for twenty-five years. There were few officers or soldiers with significant fighting experience, other than some older officers who had fought with Marlborough, such as the Earl of Stair and, curiously, King George II himself who had fought with distinction leading the Hanoverian contingent at the Battle of Oudenarde in 1708.

Contemporary authorities show the lack of military training systems in the British Army, particularly for the mounted regiments. There are clear references in the authorities to British cavalry regiments (particularly the King’s Horse and the Blues) bolting through the British infantry line during the battle, primarily due to inadequate horsemanship.

Casualties at the Battle of Dettingen:

British: 15 officers, 250 soldiers and 327 horses killed. 38 officers, 520 soldiers and 155 horses wounded.

It is hard to reconcile the low British casualties with the bombardment by 50 French guns across the river into the British flank, a couple of hundred metres away at most, at the beginning of the battle. It may be that the guns were masked for longer by the passing French troops than the descriptions of the battle indicate.

Hanover: 177 killed and 376 wounded.

Austria: 315 killed and 663 wounded.

French casualties: 8,000 (not a reliable figure but the best available)

Once the battle was over, the Pragmatic Army continued its retreat to Hanau and in due course returned to its bases in Flanders. The British casualties were left on the battlefield for the French to look after.
