What was the Western Front called in World War I?

The Western Front was the main theater of war during World War I. Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France. After the Allied Powers started fighting on the Western Front in WW I, they called it, especially the British, the "sausage machine".

The Western Front, a 400-plus mile stretch of land weaving through France and Belgium from the Swiss border to the North Sea, was the decisive front during the World War I. Whichever side won there – either the Central Powers or the Allied Entente – would be able to claim victory for their respective alliance. A victory wouldn't be easy or quick. The British troops initially likened the fighting to a "great sausage machine", consuming lives in the hundreds of thousands while remaining stubbornly in place.

From autumn 1914 two opposing lines of trenches stretched some 475 miles from Switzerland to the Channel coast. Offensives staged by both sides saw maximum advances of just 6 miles up until Spring 1918.

The air option, in short, offered a unique alternative to the carnage and futility of attrition warfare, as epitomized by the “great sausage machine” of WW I. For the first time in history, hundreds if not thousands of invincible, bombers could effortlessly leap over an opponent’s intervening ground defenses and terrorize civilians into overthrowing their own governments.
