The Battle of Ölper is a battle that took place on 1 August 1809 in Ölper, currently a district of the town of Brunswick, as part of the War of the Fifth Coalition. It pitched troops of the Kingdom of Westphalia against the Black Brunswickers under Frederick William, Duke of Brunswick-Wolfenbüttel, but ended in a tactical draw.
History
In the Battle of Jena and Auerstedt, Duke Charles William Ferdinand of Brunswick was mortally wounded. On his deathbed he nominated his son Frederick William as his successor. Although the Duchy of Brunswick-Wolfenbüttel had remained neutral in the conflict against France, Napoleon declared in 1807 that the House of Brunswick had ceased to reign, broke up the duchy and made it a part of the Kingdom of Westphalia, named the Département Oker.
Resisting this, Frederick William, equipped 2,000 troops at his own expense and offered them and his services to Emperor Franz I of Austria in the Convention of Vienna on 25 February 1809. Due to their black uniform these troops were called the Black Brunswickers. After the Battle of Wagram, Austria had made peace with Napoleon, Frederick William decided to pull his troops on their own through northern Germany to embark on the North Sea to England and on the side of England continue to struggle against Napoleon. After defeating a Westphalian infantry regiment at the Battle of Halberstadt on 29 July, the Black Brunswickers and their leader reached Braunschweig on 31 July. The troops were joyfully welcomed by the population, but on the morning following their arrival Frederick William received word that a 5,000-strong Westphalian division commanded by General Reubell was approaching from the north of the city.
The battle
The Black Brunswickers were outnumbered and were also threatened by an invading Dutch division from Halberstadt. In order not to fall between the two divisions, the Duke decided to face the Westphalians north of Brunswick, near the village of Ölper, to attempt to break through to the north.
At 14:00 the "Black Horde" moved toward Ölper, reinforced by about 200 citizens of Braunschweig, who were equipped with material looted from Halberstadt. Major Korfes destroyed the crossings over the Oker, in order to prevent flank attacks by the enemy.
An hour later, Reubell's troops appeared at Ölper; the lead Westphalian cuirassiers were immediately fired upon and retreated. The First Infantry Regiment of Westphalia now advanced on the village of Ölper. Friedrich Wilhelm left and withdrew his troops to the south and stationed artillery on a hill. From there they could counter the Westphalian infantry attack.
Now Brunswick continued with their Duke at the head of the counter-attack; Friedrich Wilhelm's horse was killed, but he himself remained unhurt. However, Captain von Rabiell, commander of the advancing companies, fell. The Black Brunswickers progressively withdrew, without having recaptured Ölper.
A direct attack on the Westphalians that followed, failed. The bold counterattack against the Hussars under Major Schrader did do damage to them and caused great confusion in the Westphalian ranks.
An artillery battle finally destroyed one of Brunswick's guns, but further attacks never came. Although the Duke was planning a night attack, Reubell had presciently already cleared the village of Ölper.
Losses
The casualty figures for the numerically far superior Westphalian troops were estimated to be between 200 and 500 men. Estimates for losses of Black Brunswicker troops vary from 40 (22 dead and 18 missing) and 86 (24 dead and 62 wounded), but these are believed to be understated.
