21st January. Our commissioners left for Pisa, and took with them many courageous young men fully determined to punish the Pisans. We hired many soldiers also, and large bodies of infantry went from the neighbourhood of Pistoia and all the country round, without pay. Everyone was ready to go there, thinking that the whole district would be sacked. No one thought much of their power of resistance; but we were mistaken, as will be seen later, for they were very persistent and united in their defence.
