On 2 August, through the passages at Vellano and Crespole, Ferrucci reached the village of Calamecca, still loyal to Florence, where he spent the last night before the battle, and from where he sent his final encrypted letter to the Dieci. This letter never reached its destination; it was rediscovered only in the nineteenth century, and today it is part of the British Library collections.
The short stay in Calamecca by Ferrucci and the last republican army is mentioned in an epigraph, dictated in the nineteenth century by the scholar Ciro Goiorani, currently placed on the side of the entrance arch to the village.
