How did Mandus' children die exactly? And why has Mandus visions about them (opening their chests and showing their hearts)?

I understood that while in Mexico, Mandus saw vision about World War I and other horrible events from future and decided that it's better for his children to die right now rather than in war. Maybe he killed them in Aztec sacrifice style by carving their hearts out.
