What Defined the Imperial German Army Uniform 1914–1918?

The Imperial German Army uniform evolved throughout World War I, but there were a few key characteristics that defined it, particularly in the early years of the war. Soldiers wore uniforms that were practical for both battle and the harsh conditions of trench warfare. The Prussian influence on military attire was strong, and the focus was on both functionality and the need to represent the power and authority of the German Empire.

1. Material and Design

The German uniform was made primarily from wool, which provided warmth and some protection against the elements. The feldgrau (field grey) color became the hallmark of the German Army’s uniform and was chosen for its camouflaging abilities. However, the M1915 greatcoat was designed for even colder conditions, offering an added layer of insulation for soldiers in the field.

2. Insignia and Ranks

Rank insignia, such as shoulder boards and collar tabs, were worn to identify soldiers' ranks and units. Medals, such as the Iron Cross, were also part of the uniform, recognizing acts of bravery and distinguished service.

3. Distinctive Headgear

The Pickelhaube helmet (spiked helmet) was an iconic piece of the uniform, though it was eventually replaced by the stahlhelm (steel helmet) as the war went on. The Pickelhaube was originally worn by cavalry and officers but later became standard for infantry units early in the war.

The M1915 Greatcoat: Design and Use

The M1915 Greatcoat was an essential piece of the Imperial German Army uniform during World War I. This heavy woolen overcoat provided warmth and protection against the cold, which was crucial for soldiers stationed in the trenches.

Key Features of the M1915 Greatcoat:

  • Material: Made from heavy wool, the M1915 greatcoat was designed to keep soldiers warm during the harsh winters and while out in the field.
  • Length: The coat typically extended below the knee, providing additional coverage and warmth. It was designed to be worn over the standard uniform, providing an extra layer of insulation against the elements.
  • Color: The greatcoat was also feldgrau, in line with the standard German Army uniform. This helped soldiers blend into the environment.
  • Buttons and Closure: The coat had a double-breasted design with large brass buttons. These buttons were usually engraved with the imperial crest.
  • Collar: The collar was high, offering additional protection from the cold. It could be folded down or left up, depending on the conditions.

The M1915 greatcoat was primarily worn by infantry, artillery, and other units exposed to outdoor elements. It was especially vital during the winter months and was one of the most practical pieces of the German soldier's kit during WWI.

WW1 German Cavalry Uniform: Details and Differences

The German cavalry was a symbol of speed and mobility in the early stages of the war. These soldiers needed uniforms that allowed for rapid movement while also providing some degree of protection in battle.

Key Features of the WW1 German Cavalry Uniform:

  • Feldgrau Tunic: The feldgrau color remained standard for the cavalry as well, though some cavalry units wore a slightly different shade or added piping for identification purposes.
  • Breeches and Boots: Cavalry soldiers wore tight-fitting breeches that allowed for ease of movement while riding horses. The breeches were often tucked into tall leather boots, providing both mobility and protection.
  • Headgear: Cavalrymen typically wore the Pickelhaube helmet with a spike on top, which was distinctive and reinforced their status as elite troops. Some cavalry units, particularly those in the later stages of the war, would wear the stahlhelm instead.
  • Cavalry Sword: One of the defining features of the cavalry uniform was the sword, which was typically worn on the left side, fastened with a leather strap. The sword was part of the traditional image of the cavalryman.

Unlike infantry soldiers who were stationary for long periods in the trenches, the cavalry was trained for speed and maneuverability. As a result, their uniform emphasized freedom of movement while also maintaining the traditional Prussian military style.

However, after examining the brass buttons with the imperial crest and cross-referencing the stitching, he confirmed it was an original piece from the war.

John’s M1915 greatcoat became a cornerstone of his collection, and he credits this find as a pivotal moment in his journey as a military collector. He notes that while the coat was costly, the historical significance and the pride of owning a piece of World War I history made it worthwhile.
