Similarly, to the eastward, the First Corps, retiring south, also got
into some very difficult forest country, and a somewhat severe rearguard
action ensued at Villers-Cotterets, in which the Fourth Guards Brigade
suffered considerably.

Gen. Joffre to defend the passages of the river as long as possible, and
to blow up the bridges in my front. After I had made the necessary
dispositions, and the destruction of the bridges had been effected, I
was asked by the French Commander in Chief to continue my retirement to

a view to taking up a second position behind the Seine. This retirement
was duly carried out. In the meantime the enemy had thrown bridges and

all along the line of the British forces and the Fifth and Ninth French
Armies. Consequently several small outpost actions took place.
