The advance of the IInd Army to Le Mans had been a series of seven days' incessant fighting. It was made at a season when the winter was in extremest severity. Ice and snow-drifts had rendered every movement one long struggle. Bivouacking was out of the question; and the troops had to seek their night shelter often at a distance of some miles in rear; their reassembling in the morning cost precious hours, and the shortness of the day then prevented their taking full advantage of their successes. Whole battalions were employed in guarding the prisoners. The roads were in such a state that the trains of the army could not be brought up; officers and men alike marched insufficiently clothed and on scanty rations. But zeal, endurance, and discipline conquered every difficulty. The army had sacrificed in this prolonged struggle 3200 men and 200 officers, the larger half belonging to the IIIrd Corps alone. Many companies fought under the command of non-commissioned officers. The French estimated their losses at 6200 men, and 20,000 taken prisoners; seventeen guns, two colours, and an abundant supply of materiel remained as trophies in the hands of the victors. After exertions so severe the troops imperatively needed some rest. The instructions from the supreme Headquarter were that the operations were not to be extended beyond a certain limit; and it was possible that the services of the IInd Army might almost immediately be required on the Seine and the Loire. Prince Frederick Charles therefore determined to follow up the retreating enemy with only a small force. On the French side, that each Corps might have a separate road for the retreat to Alencon, two Corps had necessarily to draw out westward in the first instance. On the evening of the last day's fight the XVIth Corps reached Chauffour on the Laval road, and the XVIIth Conlie on the road to Mayenne, each covered by its rear-guard. The XXIst was assembled at Ballon, on the left bank of the Sarthe. From these points all were to march in a northerly direction. General Chanzy still deluded himself with the hope of coming up by Evreux to the assistance of the besieged capital. He would have had thus to make a wide circuit--an arc by moving on the chord of which the Germans could easily have anticipated him; and in a country where all arms were available, his army, in the condition to which it was now reduced, must have inevitably been destroyed. Ultimately the defeated French army retired in the direction to the westward of the Sarthe.
