Danish M/1848 ammunition pouch | Lomme- / Ammunitionstaske M/1848
The First and Second Schleswig War (Schleswig-Holsteinischer Krieg in Germany and Treårskrigen and Anden Slesvigske Krig in Danish) is two complex and difficult topics to explain in a truthful and adequate manner.
Long story short, the Danish king was both king of the country of Denmark - and two duchies in Southern Jutland: Slesvig and Holsten. In total, the duchies, the overseas colonies and dominions of the Danish West indies (US Virgin Islands), Iceland, Greenland and Launburg was the "Kingdom of Denmark".
The duchies was an arrangement left over from the middle ages, and it worked out fine for centuries. However sentiment began changing in the early 1800s. Nationalism, domestic and foreign policy concerns and several other interlinked factors made the southernmost duchie - Holsten - to rebel - and to seek support from the largest German state - Prussia. The Fist Schleswig war was a Danish victory. Prussia was forced to redraw its troops because of Russian political pressure, the rebels lost and Holsten remained as part of the Kingdom of Denmark. Later hostilities resumed in the war of 1864 - and this time the Russians, in part because the Crimean War, were in no position to help. A combined force of Prussian and Austrian soldiers defeated the comparable small Danish army on several occasions, and the two duchies were lost until 1920 - when the northernmost parts voted "leave" and rejoined Denmark as part of the Treaty of Versailles. Holsten, and the southernmost parts of Slesvig (Shcleswig) remained (at their own will) a part of Germany.
Denmark entered the 1848-1850 war in bright red uniforms, chakos and buff white leather equipment. A look the Danish army had sported since the Napoleonic Wars. Change was needed, and a dark blue uniform, with a "cap" was introduced with black leather equipment. A noticeable difference!
The new basic equipment that was introduced had a glass water bottle covered in leather, bayonet frog and sword carrier and two small pouches for the cartridges intended for a muzzle loaded percussion cap musket.
The main idea being, that the load now was more evenly distributed and that the straps of the knapsack could be used as suspenders and distributed the weight of the cartridges and equipment evenly on both shoulders.
The pouch had a remarkable long service life, and even survived the transition from percussing cap muskets to breach loaders, and onward to brass cartridge using "modern" riffles. It was superseded by the 1867 ammunition pouch when the M/1867 Remington was introduced - but was not redrawn from service before well into the 1890s.
