In 1293, Mongol Yuan Dynasty launched an invasion to Java. The Yuan sent 1000 ships and 20,000-30,000 soldiers, but ultimately defeated in the land by surprise attack, forcing the army to fall back to the beach. In the coast, Javanese junk ships already attacked Mongol ships. After all of the troops had boarded the ships on the coast, the Yuan army battled the Javanese fleet. After repelling it, they sailed back to Quanzhou. Gunung Butak inscription from 1294 mentioned that naval commander Aria Adikara intercepting a further Mongol invasion and successfully defeating it before landing in Java. Although with only scarce information, travellers passing the region, such as Ibn Battuta and Odoric of Pordenone, however noted that Java had been attacked by the Mongols several times, always ending in failure. After those failed invasions, Majapahit empire quickly grew and became the dominant naval power in the 14-15th century. The usage of cannons in the Mongol invasion of Java, led to deployment of cetbang cannons by Majapahit fleet in 1300s and subsequent near universal use of the swivel-gun and cannons in the Nusantara archipelago. The main warship of Majapahit navy was the jong. Jong were large transport ships which could carry 500-800 tons of cargo and 200-1000 people, 70-180 meter in length. The exact number of jong fielded by Majapahit is unknown, but the largest number of jong deployed in an expedition is about 400 jongs, when Majapahit attacked Pasai, in 1350. In this era, even to the 17th century, the Nusantaran naval soldiers fought on a platform on their ships called "Balai" and performed boarding actions. Majapahit navy used breech-loading cannon called cetbang to counter this type of fighting, firing scattershots against the enemy personnel.
