I meant Archers.
Also, I'm wondering if there was a time where the Mongols were surrounded.
They were outwitted once. Beaten by wile and guile in Java, Indonesia.
in 1293, Kublai Khan of Yuan Dynasty had sent envoys to many states to ask them to put themselves under his protection and pay tribute. Men Shi or Meng-qi, one of his ministers was sent to Java, and was not well received there. Kertanagara, king of Singhasari kingdom, was offended by his brazen proposal and branded him in the face with a hot iron as was done to common thieves, cut his ears, and scornfully sent him on his way.
Kublai sent a large invasion fleet to Java with 25,000 soldiers on 1,000 ships and a year's provisions to punish King Kertanegara. They were led by Shi-Bi the Mongol, Ike Mese the Uyghur and Gao Xing the Chinese.
Having defeated the Sumatran-based Srivijayan empire in 1292, the Singhasari kingdom of King Kertanegara had become the most powerful kingdom in the area. However, Jayakatwang, Adipati (Regent) of vassal kingdom Kediri rose in rebellion and killed King Kertanegara. Kertanegara's son in law, Radin Wijaya, was somehow pardoned and given permission to build a new jungle fringe settlement. Big mistake.
When the Mongol army arrived in Java, Radin Wijaya pledged allegiance to them and offered his alliance. He duped the Mongols into believing that it was Jayakatwang the usurper who had maimed Minister Men-Qi. The Mongols believed him, because Men-Qi had reported that it was the king of Singhasari - meaning Kertanegara who had by now been dead - who had maimed him. The Mongols then combined with Radin Wijaya's army and invaded Singhasari, now ruled by the usurper Jayakatwang.
Once Jayakatwang's army was destroyed by the Mongols, Raden Wijaya returned to his newly found small kingdom, pretending to prepare his tribute settlement, leaving his allies to celebrate their victory. Shi-bi and Ike Mese allowed Raden Wijaya to go back to his country to prepare that tribute and a letter of submission, but Gao Xing disliked the idea and he warned his other two co-generals. Wijaya asked the Mongol forces to come to his country unarmed.
Two hundred unarmed Mongol soldiers led by two officers were sent to Raden Wijaya's small kingdom to collect the promised tribute, but Raden Wijaya quickly mobilised his forces again and ambushed the small Mongol convoy, killing them all. Then Raden Wijaya marched his forces to the main Mongol camp and launched a surprise attack - catching them drunk, confused and bewildered - killing many and sending the rest fleeing back to their ships.
The Mongols had to withdraw in total chaos, as the monsoon winds to carry them home would end soon, which would leave them stranded in a hostile island for six months. The Mongol army lost more than 3,000 of its elite soldiers.
Radin Wijaya's small kingdom prospered, and eventually grew into the famed Javanese-based empire called Majapahit.
