L'Isle d'Adam, north of Paris. The defense of the Somme River line south-east of Amiens left the French 13th Infantry Division, including the 8th Moroccan Tirailleurs, much depleted with each regiment falling to the size of a battalion. The French Third Army Group attached the division to the Armée de Paris and dispatched it to defend the capital city behind the Oise River. That line of resistance, the Chauvineau Line, had received some fortifications during the thirties and French engineers quickly destroyed all bridges except for a footbridge on a lock, just north of the islands in the river. The division’s three depleted regiments set up on the river line; the first German attacks began on 11 June but all assaults were repulsed. The Germans attacked again on the next day, also in vain, but the shaken III Battalion of the Moroccan regiment began to withdraw from the island as the Germans slowly infiltrated the eastern river bank by crossing the footbridge at the lock.

A Moroccan counter-attack restored the French position, but at the cost of 112 men killed. The divisional artillery gave intense support – when the batteries were allowed to emplace themselves and prepare a fire plan, French artillery doctrine could be very effective. But while the 13th Infantry Division had held its lines, its neighbors had not, pulling back from the river on either flank. With both of its flanks uncovered, the division command had no choice but to order a retreat as well.
