Castruccio takes part in the siege of Monte Catini, and according to Shelley the victory is due to him alone. (Page 153). Apparently, battles between Pisa, Lucca, and Florence often took place in Montecatini due to its geographical location. Below the hill were marsh lands, where many soldiers met unfortunate deaths, including a battle of 1315. Apparently by some accounts Dante was thought to have taken part in that battle.
