For the purposes of this, great baulks of timber were being brought into the castle from the surrounding country.

Some peasants, headed by one Brizio, who had been a squire of Guidobaldo's, availed themselves of the circumstance to capture the castle by a stratagem.

Bringing forward some great masses of timber and felled trees, they set them down along the drawbridge in such a manner as to prevent its being hoisted.

That done, an attack in force was directed against the fortress.

The place, whose natural defences rendered it practically impregnable, was but slightly manned; being thus surprised, and unable to raise the bridge, it was powerless to offer any resistance, so that the Montefeltre peasants, having killed every Borgia soldier of the garrison, took possession of it and held it for Duke Guidobaldo.
This capture of S.Leo was as a spark that fired a train.
