The Battle of San Romano was fought on 1 June 1432, in San Romano, some 30 miles outside Florence,^[1] between the troops of Florence, commanded by Niccolò da Tolentino, and Siena, under Francesco Piccinino. The outcome is generally considered favourable to the Florentines, but in the Sienese chronicles it was considered a victory. As the 1430s began Florence had found itself in conflict with the rival city state of Lucca, and her allies, Siena and Milan.

The Florentine deployed about 4,000 horse and 2,000 infantry. The clash, which lasted for some six or seven hours, consisted of a series of heavy cavalry fights. It was decided by the intervention of a second cavalry corps commanded by Micheletto Attendolo.
