At the beginning of the war, Denmark had available three infantry divisions, each of which comprised three infantry brigades with attached light cavalry and artillery.
There was also a Cavalry Division comprised of two cavalry brigades; an Army Reserve; and garrison troops in Copenhagen, the fortress of Frederica and on the Island of Alsen.
In addition to the field artillery attached to the infantry brigades, there were also ten companies of Fortress Artillery. These totalled about 600 guns between them: 175 placed in the Dannewerk; 100 at Døppel and Alsen; and 260 at Frederica and elsewhere.
This gave a total of about 38,000 men which, by the end of the war, had been increased to about 55,600 men (including seven companies of engineers).
In addition, the Danish regulars were supported by a number of Freiwilliger units and the odd foreign volunteer.
A Danish infantry brigade consisted of two regiments. A regiment consisted of two battalions, each of 800 men. A battalion was composed of four companies: a company being the tactical battlefield unit.
The Cavalry attached to an infantry division operated in a half-regiment of 350 sabres divided into three squadrons.
The Cavalry in the separate cavalry brigades operated in two regiments of six squadrons each: each regiment comprising 700 sabres i.e. approx. 110 men to a squadron.
The Cavalry consisted of a regiment of Guard Hussars; a Squadron of Royal Horse Guard (cuirassiers) and 6 regiments of Dragoon light cavalry.
A field artillery battery consisted of eight guns.
The Danish infantry used a number of rifles during the war: all of them rifled-barrel muzzle-loaders based on the Minie system. Most common was the French M1822 percussion musket converted to Minie rifling, sighted from 225 yards to 750 yards. Next was the Tapriffel M1864, or “pillar breech”, with an effective range of 250 yards and a maximum range of approx. 600 yards.
Danish infantry also carried a bayonet and the short-hilted M1854 Infantry Sword.
The Dragoons used the Rytterkarabin M1836 or M1848 muzzle-loading rifled carbines, and Rytter Sabel M1843 sabres.
The Guard Hussars used the Suhler Tapkarabin M1848, and the same sabre as above.
Danish artillerymen were issued with the Rytter Pistol M1801-02.
Field artillery used the M1863 system, comprising a mixture of 4- and 12-pdr muzzle-loading rifled-barrel, cast-iron guns.
Fortress artillery was mostly smooth-bore, and was classified into 6-, 12-, 24- and 84-pdr guns.
