In 1292 a large invasion fleet was sent to Java with over 20,000-30,000 soldiers by Kublai Khan. It did not work to well, being deceived by the Majapahit army. It was also their last chance to catch the monsoon winds home; otherwise, they would have had to wait for another six months on a hostile island. Yuan army lost more than 3,000 of their best soldiers.
What if they had not entered Majapahit territory, instead focusing on taking it by force? What effects would to conquest of Java have on Mongol policy in South East Asia?
