"Their description of the stronghold was such as to convince one that its taking was no easy matter.
"The structure was built on a spur which jutted out from the mountain side and which on three sides was too precipitate to be scaled. The overtopping main peaks were too distant to be used by our bowmen. The only approach was across a narrow neck of land which was intersected by a deep moat, crossed only by a narrow drawbridge and against which abutted the perpendicular walls of great height and thickness.
"The ex-friar said; 'A guard of six is always kept at the gate and several watchmen are stationed on the walls. I know of no way by which we can gain admission except, by deception or strategy, we first gain possession of the drawbridge and the gate.'
"'And how might that be done?'
"'This evening three of us dressed in the habit of the monastery of Agnoli, but wearing armor under our vesture, might approach the gate and ask leave to spend the night, stating we are traveling as messengers to Bologna and have gotten separated from two companions for whom we must wait. During the night you will bring your men to the chestnut wood that lies along the road as you approach the castle and place a dozen of your best archers in the trees nearest the walls. On the morrow just at six we will come to the gate as though leaving the castle and stop there talking with the watchmen. When you are ready our two companions will approach the drawbridge and join us. Then we will assault the six guards and your archers at the same time must kill the watchmen on the wall. While we hold the gate you with your men must cross the drawbridge and get to us. You know we can hold out but a few moments; there must be no delay.'
"'If we adopt this plan I want you and your companions to understand that the danger is great and you will probably be killed by the time we cross. I will force no man to assume the risk. It will be impossible for me to go as I must lead the assault. You will choose the two who go with you and I from volunteers will select two of my best men to meet you at the gate. You shall command the squad and, if successful, Sir John and your companions shall know to whom the credit is due.'
"That afternoon at four, three stalwart Italians left the camp, walking up the mountain. They were equipped in full armor and each carried a bundle under his arm.
"They crossed a rapid mountain stream near the headwaters of the Arno and were seen no more. Shortly thereafter three peaceful-looking friars came forth and took the trail leading to the castle and the pass, as they walked along chanting in a subdued tone the vesper service of their monastery.
"At twilight, dusty and sweat-stained from apparent long travel, they crossed the drawbridge just before it was raised for the night and the gates closed. When challenged by the guards they asked food and shelter for the night. The corporal of the guard interrogated them as to their business in the mountains.
"'We are three of five messengers sent by our order to Bologna. One of the other two was taken sick and forced to remain in the village overnight and a companion stayed with him; they will meet us here or in the pass on the morrow.'
