IX Corps (Grande Armée): The IX Corps of the "Grande Armée" was the name of a French military formation that existed during the Napoleonic Wars.  The corps was first formed in 1806 from German troops allied with the First French Empire and Emperor Napoleon appointed his brother Jérôme Bonaparte as commander.  During 1807, elements of the corps besieged several Prussian fortresses.  The corps was revived as an all-Saxon unit in 1809 and leadership given to Marshal Jean-Baptiste Bernadotte.  The corps fought at Linz-Urfahr and Wagram.

Battle of Raab: The Battle of Raab (Hungarian: "Győri csata") was fought on June 14, 1809 during the Napoleonic Wars, between Franco-Italian forces and Habsburg forces.  The battle was fought near Győr (Raab), Kingdom of Hungary, and ended in a Franco-Italian victory.  The victory prevented Archduke John of Austria from bringing any significant force to the Battle of Wagram, while Prince Eugène de Beauharnais’s force was able to link up with Emperor Napoleon at Vienna in time to fight at Wagram.  Napoleon referred to the battle as "a granddaughter of Marengo and Friedland," as it fell on the anniversary of those two battles.

Battle of Dresden: The Battle of Dresden (26–27 August 1813) was a major engagement of the Napoleonic Wars.  The battle took place around the city of Dresden in modern-day Germany.  With the recent addition of Austria, the Sixth Coalition felt emboldened in their quest to kick the French out of Central Europe.  Despite being heavily outnumbered, French forces under Napoleon scored a modest victory against the Allied army led by Field Marshal Schwarzenberg.  However, Napoleon's victory did not lead to the collapse of the coalition, and the lack of effective French cavalry units precluded a major pursuit.  A few days after the battle, the Allies surrounded and captured a French corps at the Battle of Kulm.

Austrian Empire: The Austrian Empire (Austrian German: "Kaiserthum Oesterreich" , modern spelling "Kaisertum Österreich ") was a Central European multinational great power from 1804 to 1867 created by proclamation out of the realms of the Habsburgs.  It was the third most populous empire after Russia and France, as well as the largest and strongest country in the German Confederation.  Geographically, it was the second largest empire in Europe after the Russian Empire (621,538 square kilometres [239,977 sq mi]).  Proclaimed in response to the First French Empire, it overlapped with the Holy Roman Empire until the latter's dissolution in 1806.  The "Ausgleich" of 1867 elevated Hungary's status.  It became a separate entity from the Empire entirely, joining with it in the dual monarchy of Austria-Hungary.

XIV Corps (Grande Armée): The XIV Corps of the "Grande Armée" was the name of a French military formation that existed for several months during the Napoleonic Wars.

The formation was made up of four French infantry divisions, one cavalry division, and supporting artillery.  The corps was stationed near Dresden to watch the passes of the Erzgebirge Mountains, which were the border between the hostile Austrian Empire and the allied Kingdom of Saxony.  Gouvion Saint-Cyr's corps played a major role in Emperor Napoleon's victory at the Battle of Dresden in late August.  Since it was assigned to garrison Dresden, the XIV Corps missed the Battle of Leipzig in October.  Isolated after Napoleon's decisive defeat at Leipzig, the unit endured the Siege of Dresden which ended in November with a French surrender.

9th Light Infantry Regiment: The 9th Light Infantry Regiment (9e régiment d’infanterie légère) was a French army regiment.  One of the most notable infantry regiments in the Napoleonic Wars, it was awarded the title "Incomparable" by Napoleon Bonaparte after their brilliant performance at the Battle of Marengo on 14 June 1800.  The regiment went on to serve with distinction in the [Ulm Campaign], at the Battle of Dürenstein (11 November 1805), the Jena Campaign (1806), and the Battle of Friedland (14 June 1807).  The regiment then served in the Peninsular War taking a notable role at the Battle of Talavera 27–28 July 1809 and the Siege of Badajoz (1812).  Battalions from the regiment also fought on the Wagram Campaign (1809), at the Battle of Leipzig (16–19 October 1813), and Napoleon’s campaigns in France (1814).  During the Hundred Days the 9th Light fought at Battle of Ligny (16 June 1815) and the Battle of Wavre (18–19 June 1815).  The regiment was disbanded in the aftermath of the Bourbon Restoration.

XIII Corps (Grande Armée): The XIII Corps of the "Grande Armée" was the name of a French military formation that existed during the Napoleonic Wars.  The corps was formed in the spring of 1813 and Marshal Louis-Nicolas Davout was appointed as its commander.  The corps included three French infantry divisions and attached cavalry.  In the spring campaign the corps was assigned to defend northern Germany.  Accordingly, Davout seized Hamburg and prepared to defend it against the Allies.  In September 1813, one brigade was defeated at the Battle of the Göhrde by the Allies.  After Emperor Napoleon's decisive defeat at the Battle of Leipzig in October, the XIII Corps became isolated in Hamburg.  An Allied army under Levin August, Count von Bennigsen initiated the Siege of Hamburg in December.  Under Davout's leadership, the corps repelled three attacks in February 1814 and a fourth attack in April.  Davout was only persuaded to surrender in mid-May by direct orders from the new French government after Napoleon abdicated.  Thanks to the iron discipline of Davout, the behavior of the XIII Corps soldiers toward the citizens of Hamburg was exemplary, compared to the usual rough treatment non-combatants often received from French soldiers of the era.
