From Halopedia, the Halo wiki
Bibjam was a veteran warrior, though his age affected his combat skills. Despite the Unggoy's lowly status within Jul 'Mdama's reformed Covenant, Bibjam served as a squad leader of a Sangheili unit, of which Dham 'Mashatt was a member of. Bibjam had attained a leadership position due to the respect that he had garnered from many Sangheili. Bibjam led his unit into many battles throughout the Blooding Years, mourning those that died along the way while the Sangheili he commanded revelled in their own glory.
As the war dragged on, Bibjam became increasingly more concerned with protecting the lives of those under his command. Believing that the Covenant was doomed, Bibjam contacted the Swords of Sanghelios and informed them of the Covenant's movements, believing that surrendering to the Swords of Sanghelios was their only opportunity for survival. When the Sangheili under his command learned of his betrayal, they confronted him. Bibjam claimed that he believed that he had found a way to save them all: allowing themselves to be captured by the Swords of Sanghelios. However, those under his command disagreed and 'Mashatt reluctantly killed him with his Type-1 energy sword, though the Sangheili could not look Bibjam in the eyes as he impaled the Unggoy.
