Who is the first person that the reader can assume is dead in Chapter 2 of "Lord of the Flies"?
Well, it seems to me that the below quote from Ralph inspires the thought of the children who have died on the plane:
'The plane was shot down in flames. Nobody knows where we are. We may be here a long time.' The silence was so complete that they could hear the fetch and miss of Piggy's breathing.
Yet the real deaths come at the end of the chapter. Piggy tells Ralph that they don't know how many people were on the island:
'I told you to. I told you to get a list of names!''How could I,' cried Piggy indignantly, 'all by myself? They waited for two minutes, then they fell in the sea; they went into the forest; they just scattered everywhere. How was I to know which was which?' Ralph licked his pale lips.
'Then you don't know how many of us there ought to be?' 'How could I with them little 'uns running round like insects?
Piggy then realises that the boy with the birthmark on his face, who spoke at the first meeting, is missing:
'That little 'un-' gasped Piggy-'him with the mark on his face, I don't see him. Where is he now?'
He never reappears in the novel. It's pretty clear - I think - that he, and however many anonymous other littluns, die in the fire.
Hope this helps!
