The Battle of Sarikamish was an engagement between the Russian and Ottoman empires during World War I. It took place from December 22, 1914 to January 17, 1915 as part of the Caucasus Campaign.
The outcome was a Russian victory. The Ottomans employed a strategy which demanded that their troops be highly mobile and to arrive at specified objectives at precise times. This approach was based both on German and Napoleonic tactics. The Ottoman troops, ill-prepared for winter conditions, suffered major casualties in the Allahuekber Mountains.
Afterward, Ottoman leader Enver Pasha publicly blamed his defeat on Armenians and the battle served as a prelude to the Armenian Genocide.
French Cuirassiers only a year before WWI would begin, looking much the same as they did under Napoleon; ca. 1913
And for most of that first year of fighting in WWI, they continued to look like this. French soldiers were massacred because of these dated outfits.
At the outbreak of war the French Army retained the colourful traditional uniforms of the nineteenth century for active service wear. These included conspicuous features such as blue coats and red trousers for the infantry and cavalry. The French cuirassiers wore plumed helmets and breastplates almost unchanged from the Napoleonic period. From 1903 on several attempts had been made to introduce a more practical field dress but these had been opposed by conservative opinion both within the army and amongst the public at large. In particular, the red trousers worn by the infantry became a political debating point. Adolphe Messimy who was briefly Minister of War in 1911-1912 stated that “This stupid blind attachment to the most visible of colours will have cruel consequences”; however, in the following year, one of his successors, Eugène Étienne, declared “Abolish red trousers? Never!”
British soldier with experimental body armor meeting with his medieval counterpart; ca. October 1917
Before the First World War, no military used true protective helmets; Pith helmets and Pickelhaubes technically are helmets, but offer very little protection against bullet fragments and shell splinters. Similarly, any armor used previously to the First World War would be of medieval-inspired designs, for instance in the armor found on heavy cavalry. Even the French helmet from that conflict was designed with medieval aesthetics in mind.
In the First World War context, modern body armor would have primarily been used for machine gunners and others in static positions exposed to heavy small arms fire. This, though, is the most modern in appearance and design that I’ve seen – the groin protector is surprisingly sophisticated.
The First World War was the true introduction of so much modern military equipment on a vast scale: helmets and body armor designed for modern threats, gas masks, tanks, fighter and bomber aircraft, light machine guns, submachine guns, semi-automatic battle rifles, and more. The Second World War, with the exception of the nuclear bomb, offered more incremental improvements than revolutionary ones.
German soldiers on outpost duty near Antwerp, sharing their food with Belgian orphans, published in 1915.
The basic Pickelhaube, as seen in the photo, was made of hardened (boiled) leather, given a glossy-black finish, and reinforced with a metal trim. Starting in 1892, a light brown cloth helmet cover, the M1892 Überzug, was issued for use during manoeuvres and active service. The Überzug was intended to protect the helmet from dirt and reduce its combat visibility, as the metallic fittings were highly reflective. As you mentioned regimental numbers were then sewn or stencilled onto the front of the cover.
This photo was most likely staged to generate evidence that countered Great Britain’s aggressive propaganda campaign against the German occupation of Belgium. Given this assumption there would be little reason for these men to don their Überzug.
As the war progressed, and Britain’s blockade limited Germanys leather supply, the economic factors you mentioned drove the government to produce Pickelhauben from thin sheet steel. However by 1915, as demand rapidly outpaced supply, pressurized felt and even paper was used to construct pickelhauben
By 1916, the Pickelhaube was slowly replaced the the new Stahlhelm (steel helmet) which offered greater over-all head protection.
Today in 1918, Manfred von Richtofen, World War I’s greatest flying ace, was shot down in his Red Fokker Triplane by a single bullet through his heart. Here is the Red Baron in a sweater in happier times; ca. 1917
He landed in enemy territory, and the RAF gave him a funeral with full military honors, befitting a legendary military aviator such as himself. It’s strange how a sense of professional respect can transcend the hatred of enemies, especially in the case of an enemy who had personally killed so many RAF pilots.
He was a dangerous enemy, but he was truly admired.
