There being no one now to oppose their advance, the three walked to the gates of the city, which had been closed against them. The gates were of iron and heavily barred, and upon the top of the high walls of the city a host of the warriors now appeared armed with arrows and spears and other weapons. For Buzzub had gone straight to the palace of King Cos and reported his defeat, relating the powerful magic of the boy, the fat King and the goat, and had asked what to do next. The big captain still trembled with fear, but King Gos did not believe in magic, and called Buzzub a coward and a weakling. At once the King took command of his men personally, and he ordered the walls manned with warriors and instructed them to shoot to kill if any of the three strangers approached the gates. Of course, neither Rinkitink nor Bilbil knew how they had been protected from harm and so at first they were inclined to resent the boy's command that the three must always keep together and touch one another at all times. But when Inga explained that his magic would not otherwise save them from injury, they agreed to obey, for they had now seen enough to convince them that the Prince was really protected by some invisible power. As they came before the gates another shower of arrows and spears descended upon them, and as before not a single missile touched their bodies. King Gos, who was upon the wall, was greatly amazed and somewhat worried, but he depended upon the strength of his gates and commanded his men to continue shooting until all their weapons were gone. Inga let them shoot as much as they wished, while he stood before the great gates and examined them carefully. "Perhaps Bilbil can batter down the gates, suggested Rinkitink. "No," replied the goat; "my head is hard, but not harder than iron." "Then," returned the King, "let us stay outside; especially as we can't get in." But Inga was not at all sure they could not get in. The gates opened inward, and three heavy bars were held in place by means of stout staples riveted to the sheets of steel. The boy had been told that the power of the Blue Pearl would enable him to accomplish any feat of strength, and he believed that this was true. The warriors, under the direction of King Gos, continued to hurl arrows and darts and spears and axes and huge stones upon the invaders, all without avail. The ground below was thickly covered with weapons, yet not one of the three before the gates had been injured in the slightest manner. When everything had been cast that was available and not a single weapon of any sort remained at hand, the amazed warriors saw the boy put his shoulder against the gates and burst asunder the huge staples that held the bars in place. A thousand of their men could not have accomplished this feat, yet the small, slight boy did it with seeming ease. The gates burst open, and Inga advanced into the city street and called upon King Gos to surrender.
