As the German Ulanen had the same kind of headgear at the outbreak of WWI-August 1914, it was often difficult to recognise Belgian Lansiers/Lanciers (English: lancers) from German Ulanen... The Tschapka, the lance with pennant....Several cases of friendly fire occured. So: At the end of August 1914 the Belgian Lancers shelved the Tschapka. From then on they had to wear the side cap. In 1915 the khaki (British type) uniform replaced the old uniforms and in autumn 1915 the-French pattern-Adrian steel helmet was adopted.
Sure it has a good home! These are rare! August 4th 1914: Trooper Antoine Fonck of the 2nd Lancers Regiment was the first Belgian soldier to fall when the Germans crossed the German-Belgian border. After WWII: My father was a Tanker in this proud Regiment. "Meurt premier comme devant"-"Die first as before" was the devise on the "silver" insigna on white shield on his black beret. Two crossed lances with pennants.
