TheBattle of Gefrees was fought on 8 July 1809 during theWar of the Fifth Coalition between a joint force of Austrians and Brunswickers under the command ofGeneral Kienmayer and a French force under the command ofGeneral Junot, Duke of Abrantès. The battle ended in victory for the Austrians who avoided being trapped by Junot and a force of Saxons and Westphalians led byJérôme Bonaparte, King of Westphalia. After Jérôme's troops were defeated at theBattle ofHof, the Austrians effectively had control over all ofSaxony. However the victory was in vain, due to the major Austrian defeat atWagram and theArmistice of Znaim.^[1]

WhenAustria declared war onFrance and her allies, includingSaxony, on 9 April 1809, a small force of Austrians together with a force of Brunswickers under the command ofFrederick William, The Black Duke was based inTheresienstadt,Bohemia (now Terezín, Czech Republic) and acted as a defensive force whilst the bulk of the Austrian army was engaged in southern Bavaria and Italy. There was little action in the region until 25 May, when a Saxon force underColonel von Thielmann invaded Bohemia. In response Duke Frederick William invaded Saxony and took the city ofZittau, forcing von Thielmann to retreat back toDresden.

After theBattle of Aspern-Essling,Archduke Charles reinforced the Austrian troops in Bohemia to a total strength of over 12,000 men and ordered a diversionary attack into Saxony. These Austrian reinforcements entered Saxony on 10 June and by the third day, an Austrian force of over 6,000 men under Major Am Ende captured the capital,Dresden. Von Thielmann and his Saxons were forced back to Gorbitz, whilst the Saxon Royal Family hurriedly fled west. Meanwhile, another force of 6,000 men underPaul von Radivojevich wheeled south intoBavaria, another French ally, capturingBayreuth on 14 June. From here, Radivojevich could threaten an invasion of theKingdom of Württemberg or an attempt to reinforce theTyrolean uprising.

On 22 June, in face of the worsening situation in Saxony and northern Bavaria, Napoleon's brotherJérôme, who was also King of Westphalia, leftKassel with a force of 15,000 men including his Royal Guard Division. On the same day the Austrian forces had occupiedLeipzig but were quickly forced to retreat by the arrival of Jérôme's troops. By 26 June, Jérôme had retaken the city and two days later the Westphalians clashed with the Austrians and Brunswickers for the first time.

In addition, General Junot had arrived inFrankfurt and took command of the Corps of Observation of the Elbe, an army hastily assembled to guard theConfederation of the Rhine. Deciding to seize the initiative rather than engaging in a defensive campaign, Junot began marching east to confront Radivojevich. Outnumbered, Radivojevich chose to fall back towards am Ende's troops to the north. Meanwhile, Jérôme's forces had retaken Dresden forcing am Ende's to form a new defensive line further south.

In an attempt to reclaim their lost momentum, the Austrian and Brunswicker troops were reorganised into the new XI. Corps and placed under the command of General Michael von Kienmayer, who had arrived with reinforcements. However, on the same day Kienmayer took up his command, Jérôme had left Dresden and headed south in pursuit of am Ende. Kienmayer and his 15,000 troops had found themselves dangerously positioned in the middle of a Franco-Westphalianpincer movement.

However, what followed was the most successful series of battles for the Austrians in over a decade. Jérôme was slow in his pursuit, allowing Kienmayer to head south and confront Junot. The Austrians first managed to stop Junot's advanced guard and then engaged Junot's main force on 8 July 1809 at Gefrees. This was the largest battle on the northern front during the whole war and ended in a decisive victory for the Austrians.

At Gefrees, the Austrians under Kienmayer had 2 regiments of regularGrenzer troops (about 5,300 men) and several hundred irregularLandwehr militia. The Black Brunswickers remained to the north guarding against any move by Jérôme and were not engaged at Gefrees. The French under Junot, on the other hand, had 2 regular line infantry regiments (about 6,000 men), a Bavarian depot battalion (about 1,000 men), and adragoon regiment (about 500 men and horses). However, Junot's Corps of Observation of the Elbe were mainly conscripts who were poorly trained in comparison to the Austrian Grenzers. In particular, Junot's cavalry was not able charge effectively, therefore failing to exploit the lack of Austrian cavalry, and allowing the Austrians to remain in line formation. This meant the Austrians were able to deliver heavy and sustained volley fire throughout and by the end of the day, most of the French infantry had fled the field of battle. The Austrians had only suffered minimal casualties, whilst inflicting a substantial blow against the French. Junot's pursuit was not only stopped, but he was forced to retreat toAmberg.

With the southern pincer defeated, Kienmayer turned his attention to Jérôme who was still slowly advancing south. He rejoined with the rest of his forces, including the Black Brunswickers, and finally engaged Jérôme's forces on 11 July at Hof. Jérôme had been expecting to fight an Austrian army being pursued by Marshal Junot. Instead, Jérôme found himself outnumbered and facing an army buoyed by a recent victory.

Jérôme, sensing defeat was inevitable, ordered a general retreat toSchleiz and the battle was merely a rear guard engagement. Duke Frederick William and his Black Brunswickers gave chase forcing Jérôme all the way back toErfurt and the western borders of Saxony. The Austrians retook Dresden and the whole of Saxony had been evacuated. However, by the time Jérôme and his army had arrived safely inErfurt, news of the French victory atWagram and the resultingarmistice atZnaim had reached Saxony. The Austrians were forced to concede all their gains and Jérôme and his Westphalians headed safely back toKassel.

Duke Frederick William, however, was appalled by theArmistice of Znaim. He had hoped with the help of Kienmayer and the Austrians to start a popular uprising against Napoleon in northern Germany. Refusing to agree to the peace between Austria and France, the Black Duke decided to take matters into his own hands and make for theNorth Sea with his 2,000 troops. He still hoped to start popular uprising and in the following weeks, the Black Duke caused Jérôme major problems, defeating his Westphalian troops twice at the battles ofHalberstadt andÖlper, as well as reinforcing his army with Westphalian deserters from both battles. The Black Brunswickers even managed to temporarily retake the city of Brunswick but Jérôme had ordered three generals to find and destroy the Duke Frederick William's forces. Despite this the Black Brunswickers still managed to reach the coast and were evacuated to theIsle of Wight in August 1809 on the ships used to land troops atWalcheren.
