The most important part of the story was when they got rescued. The first wave of rescuers came with a fireboat, supply ship, and two coast guard ships. The plan was to spray the rats of the lighthouse. But that sadly failed because the rats tried to swim to the fireboat and the firemen had to fight instead of spray. The next morning the second wave of rescuers came with a tug that had meat, a fireboat, and a patrol boat. The tug lured the rats to the meat as the rescuers poured gasoline onto the meat. Then the patrol boat fired a shell that the meat and all of the rats got blown up and those who didn't got killed by sharks. Then the lighthouse keepers were able to get escorted back to the mainland. This part of the story was the climax and without it, the lighthouse keepers would still be stuck.
Help! Save Us!
"After a short reconnaissance, the fireboat picked her way slowly through the reefs until she was close to us, then turned her powerful jet of water on the rats. The heavy stream tore the rats from their places and hurled them screaming intothe water, where the sharks gulped them down."
"Furthermore, some of them, instead of returning to the rocks, boarded the fireboat and the men were forced to battle them hand to hand. They were true rats of Holland, fearing no man, fighting for the right to live!"
"To the last rat, our besiegers deserted the rock, swam out, and boarded the barge reeking with the scent of freshly cut meat."
"The tug dragged the barge about a mile from shore, where the fireboat drenched the barge with gasoline. A well-placed incendiary shell from the patrol boat set her on fire."
