Early 1293, the Mongol naval forces arrived on the north coast of Java (near Tuban) and on the Brantas River mouth to flank what they thought was Singhasari. Raden Wijaya found the opportunity to use the unsuspecting Mongols to overthrow Jayakatwang. Raden Wijaya's army allied with the Mongols in March 1293 and battle ensued between Mongol forces against Daha forces in the creek bed of Kali Mas river, a distributary of Brantas River, which was followed by the battle of Mongol forces against Daha forces that attacked the Majapahit regional army led by Raden Wijaya. The Mongols then stormed Daha and Jayakatwang finally surrendered and was executed.
