The city of Sinigalia is distant from the foot of the mountains a little more than a bow-shot and from the shore about a mile.

On the side opposite to the city runs a little river which bathes that part of the walls looking towards Fano, facing the high road.

Thus he who draws near to Sinigalia comes for a good space by road along the mountains, and reaches the river which passes by Sinigalia.

If he turns to his left hand along the bank of it, and goes for the distance of a bow-shot, he arrives at a bridge which crosses the river; he is then almost abreast of the gate that leads into Sinigalia, not by a straight line, but transversely.

Before this gate there stands a collection of houses with a square to which the bank of the river forms one side.
The Vitelli and Orsini having received orders to wait for the duke, and to honour him in person, sent away their men to several castles distant from Sinigalia about six miles, so that room could be made for the men of the duke; and they left in Sinigalia only Oliverotto and his band, which consisted of one thousand infantry and one hundred and fifty horsemen, who were quartered in the suburb mentioned above.
