"March or Die" — A Tradition
“March or die” (Marche ou crève) is the famous unofficial motto and operational ethos of the French Foreign Legion. Rooted in 19th-century North African colonial campaigns, it symbolizes extreme physical endurance, absolute mission completion regardless of hardship, and the consequence of failing to keep pace in harsh desert environments. The ethos dictates that legionnaires push past physical breaking points because abandoning a comrade or failing a designated task is completely unacceptable.
The Legion famously marches at 88 steps per minute (the pas légionnaire), much slower than the standard 120 steps per minute of regular French military units. This deliberate, heavy cadence reflects a history of moving steadily through deep desert sand and an attitude of not rushing toward mortal danger. Because of its marching speed, the Foreign Legion is always the last unit marching in any joint parade of the French Army.
During World War I, the French Foreign Legion shifted from colonial policing to intense trench warfare on the Western Front. Over 43,000 global volunteers—including Italians, Russians, and Americans—joined specialized marching regiments, suffering catastrophic casualty rates while earning some of the French army’s highest military honors. On the Western Front, Legion units fought heavily in Champagne, Artois, Verdun, and the Somme, often assigned to high-risk assault objectives. In late 1914, Italian volunteers of the unique Garibaldian Legion (Légion Garibaldienne) fought valiantly in the Argonne before disbanding. Smaller Legion deployments fought in Serbia, Salonika, and Gallipoli. By November 1915 two Foreign Legion units had been merged into the “Régiment de marche de la Légion étrangère” (Foreign Legion Marching Regiment, RMLE) .

March or Die on the Western Front
Did these new Foreign Legionnaires, who served in Europe during the Great War adhere to the standards of "March or Die" as followed by the Legion's old veterans of Morocco or Indochina? Recruits underwent intense conditioning focused on long-distance endurance with heavy field packs, rigid unit synchronization, and the signature slow ceremonial pace of 88 steps per minute set to their iconic anthem Le Boudin.
Additionally—in regards the marching part—we have this 1914 account from famed American volunteer Alan Seeger's diary that seems to resoundingly answer "Yes".
11 October
[A] seven-hour march
20 October
Short walk of 16 Kilometers in morning
9.8 km later in the day
22 October
30 km Hautvilliers to Verzy
Later, short march to Verzenay [2.4 km]
28 October
A long day's march was promised us to counteract the comfort of marching without sack. It was in fact the hardest day we have had. We marched with small and few interruptions from 6.30 in the morning to 10.30 at night, in which time we covered probably about 55 kilometers. No food except the scraps we had in our musettes. . . Arrived at Fismes after nightfall and exceedingly fatigued, expected to be cantonned there, but kept on marching through the town and out into the dark country again. . . At 10.30 we halted and were told to spread our blankets in the field beside the road. . . At midnight I lay down on the wet ground and managed to get some sleep before three, when we got up again and continued the march 10 or 12 kilometers to this wretched village, where we are lodged for the day in a dirty stable. . . Here we are just behind the lines. We are resting and go into the trenches tonight. At last we shall be under fire. [Editor's comment: This last sentence sounds like a sigh of relief.]

Combat, of course, provided its own tests of the mettle of the Legion's men. Because they were repeatedly sent into the bloodiest sectors of the front lines, entire units were often wiped out and had to be repeatedly reconstituted with fresh drafts of international volunteers. Towards the end of the war, however, a serious dearth of recruits would jeopardize the Legion’s continued presence at the Western Front. Officially 4,116 members of the Foreign Legion were killed on the Western Front and another 1,200 in other theatres of war. Thus, roughly 10 percent of those serving in the Legion between 1914 and 1918 lost their lives.
It was not by chance, therefore, that the Legion would not be affected by the general morale crisis and mutinies of the French army in spring 1917. While roughly half of the conventional French divisions on the Western Front experienced collective indiscipline or refusals to attack after the failed Nivelle Offensive, the Régiment de marche de la Légion étrangère maintained its high morale, discipline, and commitment to combat. While they weren't marching across the Sahara, the core demand of the tradition—absolute compliance, relentless stamina, and a willingness to face certain death for France—remained unchanged in the mud and barbed wire.
