who was about to pass through territory inhabited by Christians to behave peacefully, to do no harm, and not to depopulate the land of those whose rights they had come to protect; they should take, as peacefully as possible, and after having paid for it, only the food that they needed. They went forward, and as they passed from city to city, from field to field, from camp to camp, they found abundant trade everywhere, until they arrived in the province called Castoria, and there they solemnly celebrated Christmas, remaining for several days. They asked the people of the province for permission to trade, but they refused to grant permission, fearing that our men, whom they considered warriors, not pilgims, wanted to destroy their land and crush them. Angered, their restraint now turned to fury, and they seized horses, cows, asses, and whatever else was useful. Then they left Castoria and entered Pelagonia, where they came upon a fortified town of heretics, which they attacked on every side, compelling them to surrender. They then burned it to the ground, together with its inhabitants. From there they went to the river called the Baudarus. [118] Bohemund moved forward with part of his knights and left the rest in the hands of a certain one of his counts. When the emperor's army, which was not far off, learned of this, it attacked the count, who was now without the aid of Bohemund, who had gone on ahead of him, and the count's men were thrown into confusion by the attack of the enemy. When brave Tancred heard of this, he swiftly turned back, leaped into the river mentioned above, and swam back to those who were being attacked. He then assembled the nearly two thousand men who swam behind him, found the enemy, who were fighting fiercely against his own men, and attacked them with equal fierceness, quickly overcoming them. Many of them were captured and brought before Bohemund in chains. To them the prince said, "Why do you pursue my people, the people of Christ? I am not trying to overthrow your emperor." They replied, "We do nothing by our own deliberation. We are soldiers who earn money by carrying out the orders of the emperor; whatever he tells us to do we do." When the splendid man heard this, he let them go, without punishment and without ransom. This battle took place on the fourth day of the week, which among Christians is called the beginning of the fast[119]
