 Little is known of the next two rulers , Ruler 6 is named as K 'inich Tuun Chapat , he celebrated the period ending of 736 and may have died 762 . A damaged text accompanying the image of a bound captive indicates renewed warfare with Palenque during his reign , however the name of the prisoner is lost and it is unclear if it is the actual king of Palenque or merely one of his vassals . He was succeeded by Ruler 7 , about whom even less is known . Around 764 Toniná defeated Palenque in battle .
