out some of Castniccio's officials and partisans, and killing others, they restored the city to its freedom. The news of this greatly angered Castruccio, and taking leave of Enrico, he pressed on in great haste to Pistoia. When the Florentines heard of his return, knowing that he would lose no time, they decided to intercept him with their forces in the Val di Nievole, under the belief that by doing so they would cut off his road to Pistoia. Assembling a great army of the supporters of the Guelph cause, the Florentines entered the Pistoian territories. On the other hand, Castruccio reached Montecarlo with his army; and having heard where the Florentines' lay, he decided not to encounter it in the plains of Pistoia, nor to await it in the plains of Pescia, but, as far as he possibly could, to attack it boldly in the Pass of Serravalle. He believed that if he succeeded in this design, victory was assured, although he was informed that the Florentines had 30,000 men, whilst he had only 12,000. Although he had every confidence in his own abilities and the valour of his troops, yet he hesitated to attack his enemy in the open lest he should be overwhelmed by numbers. Serravalle is a castle between Pescia and Pistoia, situated on a hill which blocks the Val di Nievole, not in the exact pass, but about a bowshot beyond; the pass itself is in places narrow and steep, whilst in general it ascends gently.
