The passes being deep with snow, so as to be almost impassable for artillery and baggage, Lobcowitz gave up all thought of entering Naples by the coast road, which was the only clear one, and very unwisely recalled Count Brown with his forces; and as soon as they joined, began his march by the way of Umbria and the Campagna di Roma, with 6000 horse and 20,000 foot. Among the former were 2000 hussars; among the latter were some irregulars, or free companies of what Buonamici, in his _Commentaries_, styles "Condemned persons and deserters, who, despairing of pardon, and urged by the prospect of plunder, panted for an opportunity of coming to blows with the enemy." This small army advanced in three columns, two days' march apart, that the people might not be oppressed. Brown commanded the first. Advancing by Spoleto, Terni, and Narni, they reached Castellana, and held a council of war, at which Brown, the Cardinal Alessandro Albani, and the Bishop of Gurck assisted. A stormy debate ensued, and nothing was decided upon. Meanwhile the alarmed King of Naples, with the combined armies of Naples and Spain, was encamped on the hill of Anagni, in the Campagna di Roma. The Spaniards under Count Gages consisted of eleven battalions of infantry, three regiments of cavalry, under the Duke of Atri, five hundred horse-archers, and three hundred of the Duke of Modena's archer-guards (archers, of course, but by name); with the _Irish Brigade_, and a regiment of hussar deserters. The Neapolitan army consisted of eighteen battalions of foot and five regiments of horse. The vanguard was composed of light-armed mountaineers. The artillery was commanded by the veteran Conte di Gazola. Lobcowitz and Brown now began their march towards Rome; crossed the Tiber at Teverone, and halted at Marino, where of old stood the villa of Caius Marius. After a great deal of severe marching, counter-marching, and skirmishing, the prince resolved on assailing the chiefs of the allies in their head-quarters, which they had established in Viletri; and this daring enterprise he committed to Brown, his most active and able general.
