In the 1792-1796 period, Baden was allied to Austria-Hungary during the war against Revolutionary France. Elector Carl Frederick later allied Baden to France by signing the Treaty of Ettingen (1805). Baden joined the Confederation of the Rhine in July 1806 and Carl Frederick then became a Grand Duke. Carl Frederick died in 1811, being succeeded by his grandson Charles (who was married to Stephanie de Beauharnais, the step-daughter of Napoleon Bonaparte). Baden continued to support the French cause until after the battle of Leipzig (1813), when it switched allegiance to the Allies.
The Baden army consisted of the Garde du Corps squadron, a Leib Garde grenadier battalion, four Line Infantry regiments (with two field battalions each), two cavalry regiments (Hussars and Light Dragoons), a battalion of rifle-armed Jäger (Light Infantry), plus a Foot and a Horse artillery battery. The Foot battery had six 6pdr guns and two 7pdr howitzers; the Horse battery had four 6pdr guns and two 7pdr howitzers. After April 1808, the Foot battery exchanged its 6pdrs for captured Spanish 8pdrs.
Each Baden Line Infantry battalion should consist of either 20 figures (4 five-figure companies) or 16 figures (4 four-figure companies). The Leib Garde grenadier battalion had five companies.
The Baden infantry battalions serving in Spain (the 1st Battalion, 4th Regiment; and the 2nd Battalion, 3rd Regiment) should be organised along French lines, with each (18-figure) battalion thus having 4 three-figure Fusilier companies, 1 three-figure Grenadier company and 1 three-figure Voltigeur (Light Infantry) company.
The Baden Light Cavalry regiments (Hussars and Light Dragoons) should each be represented on the tabletop by 1-4 squadrons: each squadron having four figures. The Hussars should be classed as Guard Light Cavalry (but will not exist after the 1812 campaign). The Light Dragoons should be classed as Veteran Light Cavalry (and will be available from 1803 onwards, having been transferred to Baden, from Bavaria, after a territorial adjustment).
The Garde du Corps squadron should have 3 or 4 figures; and though they did not wear cuirasses, they should be classed as Guard Heavy Cavalry.
For game purposes, all the guns in an artillery battery will be deemed to be the same type; thus the Baden artillery (July 1806 – April 1808) should consist of a Horse battery with six 6pdr field guns and a Foot battery with eight 6pdr field guns. On the tabletop, one of these two batteries may instead substitute its field guns for 7pdr howitzers.
From May 1808 onwards, the Baden artillery should consist of a Horse battery with six 6pdr field guns and a Foot battery with eight 8pdr field guns. Again, one of these two batteries may instead substitute its field guns for 7pdr howitzers.
During the 1813 campaign, the Foot Artillery was divided into 2 four-gun batteries, each being assigned to a different Baden infantry brigade (and if both four-gun batteries are present in the game, both may have 8pdr field guns, or one of the four-gun batteries may have 7pdr howitzers instead).
