With only 25,000 soldiers at his command, Ban decided to first attack a small kingdom calledSuoche because it had formed an alliance with the Huns. The king of Suoche sent for help fromQiuci, a kingdom to the north. The king of Qiuci immediately led a troop of 50,000 men to fightthe Ban army. Ban realized he could not win a battle with the joined forces of the two kingdoms if he foughtthem head-on. So, he sent out people to spread rumors that his army had decided to retreat. Heordered part of the army to run away to the east and he himself led the remaining troops toretreat pell-mell to the west. The Qiuci king was overjoyed when he heard the news and led his troops to chase Ban overnight. Ban and his troops didn't go far. When the night fell, they left the main road and hid themselvesin nearby woods. After the Qiuci king and his men rushed past them to the west, Banimmediately ordered his troops to march back to the Kingdom of Suoche. Meanwhile, his troopswho had earlier left for the east also came back and they launched a surprise attack againstSuoche. Before dawn, the small kingdom's defenses collapsed and the king surrendered. 本文来源：https://www.wddqw.com/doc/4ce079bb9a8fcc22bcd126fff705cc1754275f42.html
