Montreuil, British Expeditionary Force Command.
Haig was frantically busy inside a corner of a collapsed wall, with wounded soldiers being carried away and routed soldiers being replaced everywhere outside.
Shells whistled through the air and exploded nearby.
The noise of fighter planes was constant, occasionally diving down to strafe the ground, causing the British Army below to scream in misery.
The British Army's resistance in Montreuil was extremely difficult.
Their artillery range couldn't match the enemy's 105MM howitzers, they had fewer planes than the enemy, and their tanks were not as advanced as the enemy's.
Most critically, nearly all of the British Army's defenses were oriented towards Belgium; no one expected the Germans to advance along the River Somme and then attack from behind.
