Deadly North Sentinel Island

Late on the night of August 2, 1981, a Hong Kong freighter navigating the choppy waters of the Bay of Bengal ran aground on a submerged coral reef. The ship, called the Primrose, was hopelessly stuck. But there was no danger of it sinking, so after radioing for assistance, the captain and crew settled in for a few days' wait until help arrived.

The following morning, as it became light, the sailors saw an island a few hundred yards beyond the reef. It was uninhabited, as far as anyone could tell: There were no buildings, roads, or other signs of civilization there -just a pristine, sandy beach and behind it, dense jungle. The beach must have seemed like an ideal spot to wait for a rescue, but the captain ordered the crew to remain aboard the Primrose. It was monsoon season, and he may have concerned about lowering the men into the rough sea in tiny lifeboats. Or perhaps he'd figured out just which tiny island lay beyond the reef: It was North Sentinel -the deadliest of the 200 islands in the Andaman Island chain.
