The Neapolitans extended in line, and attacked; but were repulsed on the left and the centre. The two companies on the right were driven back, when Garibaldi, being victorious in other parts, proceeded with the reserve to the right, and the rout of the enemy was then completed. A strong body of royal Swiss troops, in the pay of Bomba, was present. The Republicans being destitute of cavalry, and the speedy arrival of night, saved the wrecks of the troops of Bomba. From Palestrina, Garibaldi returned to Rome. ------- THE BATTLE OF VELLETRI. A few days after, he again left Rome, with the Roman army, and was in the vanguard, having under his orders the First Italian Legion, of eleven hundred men; the Third of the line, eight hundred; fifty cavalry, and two light guns. At Valmontone he received advices that the Neapolitans were sending back their baggage and heavy artillery, and he therefore concluded that they were retreating, and pressed forward, sending notice to the principal corps. At Monte Fortino he received more positive information, and continued to advance with haste. About eight o'clock A. M. he was in sight of Velletri, which was on the road, and two miles distant. He then discovered the enemy's cavalry, in _échellon_, on the Appian Way, to protect the retreat of their army, for which they were preparing. The main body of the Neapolitan army was then at Velletri; and, as soon as Garibaldi's corps was discovered by them, the Neapolitans moved to attack it. He drew up the Third of the line, in _échellon_, by companies, near the road, which was among hills covered with vineyards, to protect his retreat in case of necessity, and to act as a reserve in case the enemy should attack. He placed the First Italian Legion on both sides of the road, in the best position he could, and thus awaited the assault of the enemy, leaving two companies in column in the road itself. The cavalry and artillery he placed in positions adapted to be most serviceable. The enemy attacked: but all their attempts were fruitless. They had many killed, and were finally obliged to shut themselves up in the city, on the defensive. Garibaldi's corps alone was too weak to prevent the retreat of the enemy, which was finally effected by night. The principal corps of the Roman army, of seven thousand men, under Roselli, arrived late, and tired with their march. An attempt, however, was made to attack the city in front, by charging, at the head of the First Roman Legion, with the battalion of artillery placed in a good position upon the road. The Neapolitans sustained the positions of the city, in which they remained the rest of the day. The Republicans took positions, in order to renew the attack the next day: but in the morning the Neapolitans retreated, and disappeared from Velletri.
