It is with Frederick alone that we are concerned. In 1188 he set out, at the head of one hundred and fifty thousand trained soldiers, on what was destined to prove a disastrous expedition. Entering Hungary, he met with a friendly reception from Bela, its king. Reaching Belgrade, he held there a magnificent tournament, hanged all the robber Servians he could capture for their depredations upon his ranks, and advanced into Greek territory, where he punished the bad faith of the emperor, Isaac, by plundering his country. Several cities were destroyed in revenge for the assassination of pilgrims and of sick and wounded German soldiers by their inhabitants. This done, Frederick advanced on Constantinople, whose emperor, to save his city from capture, hastened to place his whole fleet at the disposal of the Germans, glad to get rid of these truculent visitors at any price. Reaching Asia Minor, the troubles of the crusaders began. They were assailed by the Turks, and had to cut their way forward at every step. Barbarossa had never shown himself a greater general. On one occasion, when hard pressed by the enemy, he concealed a chosen band of warriors in a large tent, the gift of the Queen of Hungary, while the rest of the army pretended to fly. The Turks entered the camp and began pillaging, when the ambushed knights broke upon them from the tent, the flying soldiers turned, and the confident enemy was disastrously defeated. But as the army advanced its difficulties increased. A Turkish prisoner who was made to act as a guide, being driven in chains before the army, led the Christians into the gorges of almost impassable mountains, sacrificing his life for his cause. Here, foot-sore and weary, and tormented by thirst and hunger, they were suddenly attacked by ambushed foes, stones being rolled upon them in the narrow gorges, and arrows and javelins poured upon their disordered ranks. Peace was here offered them by the Turks, if they would pay a large sum of money for their release. In reply the indomitable emperor sent them a small silver coin, with the message that they might divide this among themselves. Then, pressing forward, he beat off the enemy, and extricated his army from its dangerous situation. As they pushed on, the sufferings of the army increased. Water was not to be had, and many were forced to quench their thirst by drinking the blood of their horses. The army was now divided. Frederick, the son of the emperor, led half of it forward at a rapid march, defeated the Turks who sought to stop him, and fought his way into the city of Iconium. Here all the inhabitants were put to the sword, and the crusaders gained an immense booty.
