Lord of the flies 12

I really didn't like the ending of this book. I believe that it was all meant to happen like this and the signal fire was a symbol and it was meant to have them be rescued. I thought it was ironic that the reason they got rescued though was because Jacks group of hunters set off a forest fire and led a boat to the island. The ending went from chaos to some what of order when the adult figure showed up on the beach after the chase through the forest with Ralph. I believe that the author chose to have the boys be rescued at the end instead of having Ralph die or anything of that matter is because the author didn't want to keep the chaos going, and I feel like if he continued the book things would have gotten worse if Ralph died.
