This Wehrmacht Stahlhelm M40 represents an extraordinary testimony to the complex military and political circumstances during the Liberation of Belgium in autumn 1944. The helmet combines the histories of two opposing sides: first as equipment of the German Wehrmacht, then as a trophy and protective gear of a Belgian resistance fighter.
The Steel Helmet Model 40 was introduced in 1940 as a development of the M35 and differed from its predecessor primarily through simplified manufacturing methods. The ventilation holes were no longer laboriously stamped from the helmet body and fitted with separate parts, but simply drilled as plain holes. This rationalization enabled faster and more cost-effective production, necessary for the war-related increased demand. The manufacture in 1941-1942 falls into a phase when German armaments industry was already operating at full capacity, but had not yet experienced the extreme material shortages of the later war years.
The light green camouflage paint corresponds to common camouflage patterns used by the Wehrmacht. Interestingly, this helmet combines components from different production phases: the leather liner and interior fittings date from the early war period, while the chinstrap with Reichsbetriebsnummer (RB-Nr.) 0/0750/0100 was not manufactured until after 1943. Such combinations were quite common during the war, as damaged parts were replaced or helmets were completed with available components.
The Belgian Resistance, to which Antoine Martinet belonged, gradually developed into a significant force after the German occupation of Belgium in May 1940. Initially focused on intelligence gathering and escape assistance, the various resistance groups intensified their sabotage activities and military operations from 1943 onwards. The region around Courcelles in Hainaut province was the scene of fierce fighting during the liberation in September 1944 between German troops, Allied forces, and local resistance groups.
The painting of the helmet with the Belgian national colors black-yellow-red on both sides served as an important identification mark. In the chaotic days of liberation, distinguishing between friend and foe was vital, especially for resistance fighters wearing captured German equipment. These markings prevented tragic mix-ups by Allied troops or other resistance groups.
Autumn 1944 marked a decisive turning point for Belgium. After the Allied landing in Normandy in June and the rapid advance through France, British and American troops reached the Belgian border in early September. However, liberation did not proceed smoothly everywhere. In some areas, German units offered fierce resistance, and local resistance groups played an important role in supporting the Allied advance. The fighting claimed casualties on all sides, including among the civilian population and resistance fighters.
The handwritten paper labels affixed inside the helmet immediately after the war represent an authentic period document. The French-language inscription honors Antoine Martinet as a member of the “Valeureux resistants de Courcelles” and preserves the memory of his death during the liberation fighting. Such personal memorial pieces were common in the immediate post-war period, as relatives and comrades of fallen resistance fighters honored their memory.
From a military-historical perspective, this helmet illustrates several important aspects: the industrial production of German military equipment, the practice of reusing captured equipment by resistance fighters, the necessity of identification markings in irregular combat units, and finally the early memorial culture of the post-war period. The untouched original condition with all signs of use makes it a valuable study object for understanding the material culture of World War II and the liberation of Western Europe.
The history of this helmet reminds us that the liberation of Belgium was not achieved solely by Allied armies, but that local resistance fighters like Antoine Martinet paid a high price for their country's freedom. Every detail – from the German manufacturer's marking to the Belgian national colors to the handwritten memorial notes – tells part of this multi-layered story.
