Throughout his education, he went to school with Fernard Leger, who was also his French partner. He incorporated some geometric forms into his work. Hence, he was widely known as one of the forerunners of the cubism. He developed his style later on, which was practically modernism, and classicism. Fortunately, this was the style that lasted throughout his life and career as a painter.
He developed an innate love for artistry during his early childhood. He was able to earn a living throughout his life as a designer. His worked and paintings were a reflection of his experience during the World War 1. He was a soldier while in the French army during the war. He applied military art style to his work. He was the founder of the Company of the French art during his time. He was a leader of the army camouflage, whereby he painted artillery with the aid of cubism procedure. Some of his famous works include Marching through the Arch of Triumph, American Troops, and the Funeral of Marshal Foch.
He participated in the Champagne Offensive in 1915. After which he quickly joined the Camouflage unit under the authorization of the staff. His first work was to prepare the Somme Offensive with the British soldiers he had trained in this new style. He left the French army in late 1917, before then; he had worked with the Somme and the Oise departments. He discovered the war had changed entirely when he returned to the French lines in 1918. He soon realized that notable tanks and materials were of great value during the new phase of the war. The camouflages changed their workshops frequently because they have designed some designed some mask in that place which was based on fake trees. They hurriedly worked out kilometers of rolls and netting to conceal the spot containing implanted regiments, for just that day.
Mare documented his experiences during the war using colors, photos, paintings, and drawings. He did this in a then-small green like sketchbook that later provided some understanding of the real cause of the war. He later described how he worked as a camoufleur in sketches and drawings. He applied figurative watercolors, but they later became cubist. And this re[resented an image of modernity prior to the war. Apparently, Mare wanted to use it as a means to convey the war and his destructive power during his time.
