In the night the greater number of the men escaped towards Rome; only 300 in the palace were taken prisoners, besides forty-two horses and two pieces of cannon, 500 stand of arms, and all their materials of war. The fight had lasted twenty-four hours--from eight one day to eight the next--without a single instant's cessation of firing. It cost us between 400 and 500 men, amongst whom were some of our bravest and best officers. This was the first real struggle under the General.
We had one day's rest; but on the following night the enemy returned, and attacked the railway station at about a mile distant from Monte Rotondo, where, finding a number of our wounded, they bayoneted them in their beds, one man having twenty-seven wounds in his body. The General at once sent heavy reinforcements, and the enemy was driven back. Three days after this we marched to the Zecchenella, a large farmhouse about a mile distant from the Ponte de la Mentana, within about four miles and a half from Rome. On our approach the enemy re-crossed the bridge, blowing up one of the two bridges and mining the other. The Papal troops came again on our side of the Teverone--a river which joins the Tiber a few miles from Rome. They extended themselves as sharpshooters all along our line, amusing themselves by firing at us until the evening, we scarcely returning a shot, the General having ordered us not to do so--our aim, since we were so few, being to draw the enemy into the open country. In the night we lighted large fires, to let the people in Rome know that we were near; but the movement which we expected in the city did not take place, and we returned to Monte Rotondo the next day.
After staying there for several days, the General resolved to march to Tivoli, which was held by a strong body of our volunteers. The column, consisting of 4700 infantry, two field guns and two smaller guns, and one squadron of cavalry, commenced its march at eleven o'clock. When we had gone a mile beyond Mentana the vanguard was suddenly attacked, and we had to fall back on Mentana, so as to form our battalions in line of battle. Recovered from our first surprise, the General ordered all the troops to advance, and we retook the positions we had lost, when, just as the Papal troops were retreating on the road to Rome, the French regiments, which till now had remained hidden behind the hills, out-flanked us on the left. After some very heavy fighting, especially in the position of the haystacks in the centre, which were taken, lost, and retaken, four or five times, the General, seeing the uselessness of contending against such an overwhelming force, gave the order to retreat. We retreated from the field of battle, passing under the fire of the Chassepôts, leaving between 400 and 500 men on the field, and about the same number of prisoners in their hands, and one piece of cannon. Two battalions, numbering altogether over 400 men, shut themselves up in the old fort of Munturra, where, having exhausted all their ammunition, they surrendered in the morning. When the main body had returned to Monte Rotondo, the General gave orders that every thing should be ready to re-attack in the night; but on examining the state of our army, we found that scarcely a cartridge remained, and not a single round of ammunition for the cannon. Learning this, the General gave the order to retreat to Passo Corese, where we arrived about one in the morning, being again on Italian soil. We then proceeded to the disbandment of our troops.
