To Lamaze’s right, six divisions led by John French, the head of the British Expeditionary Force, filled the gap with the 5th Army.

[5] On September 6, 1914, like the other French generals, Beaudenom de Lamaze received Joffre's famous order to "get killed on the spot rather than retreat".

On the 7th, Gallieni visited Lamaze on Monthyon hill,[7] from where he saw the enemy "marmites" (large-caliber bombshells releasing thick black, orange and violet smoke on impact).

Over the following weeks, the General Staff stressed the need to consolidate the position north of Soissons, by extending the breakthrough achieved by the Moroccan brigade to secure this part of the front.

Lamaze expressed his reluctance, fearing that such an attack, for lack of resources, would trigger an immediate response that would jeopardize the very maintenance of his positions.

[10] Georges Painvin praised the loyal friendship of Beaudenom de Lamaze, who frequently visited Maunoury, blind and disfigured since March 1915.

He was the grandfather of Jacques Beaudenom de Lamaze, a Companion of the Liberation killed at the Battle of Bir Hakeim.
