Whats an example of irony in A Long Way Gone by Ishmael Beah?

An overwhelming irony surrounds the death of Ishmael Beah's
family in A Long Way Gone. All the while that Beah spends on the run, he
desperately wants to find his family. In every village that he and his friends encounter, Beah
first checks to see if his family has passed through the area. So, when Beah finally meets Gasemu
and learns that his family has been staying in a nearby village, he is overjoyed. Ironically,
when Beah arrives with Gasemu in the village, the rebels have beat them to it and have burned
down the entire village. No remains are found, but Gasemu tells Beah that his family had been
staying in a hut that is totally burned. This sad irony haunts Beah throughout the remainder of
his story.
