The Mongols under Kublai Khan had in 1281 ordered the Cham King Indravarman V to come to Bejing with tribute but he refuses.

The Mongols send a fleet down to attack the Cham kingdom and the Cham hide in the hills.

A year later, the Mongols send a large army (an estimated five hundred thousand strong) south to attack the Cham.

This army marches through Vietnam but without Vietnamese permission.

The Vietnamese harass the army in conjunction with the Cham.

With little to show for this display of force, the Mongol army withdraws.

Sogetu of the Jalayir, the governor of Canton, is dispatched to demand the submission of Champa.

Although the king of Champa accepts the status of a Mongol protectorate, his submission is unwilling.

In 1282, Sogetu leads a maritime invasion of Champa with five thousand men, but can only muster one hundred ships because most of the Yuan dynasty's ships had been lost in the invasions of Japan.

However, Sogetu is successful in capturing Vijaya, the Champa capital, later this year.

The aged Indravarman V retreats out of the capital, avoiding Mongol attempts to capture him in the hills.

His son will wage a guerrilla war with the Mongols for the next few years, eventually wearing down the invaders.
