The Ngatik massacre took place over two days of fighting on the atoll of Sapwuahfik in the Micronesian island chain in July 1837.
Captain C. H. Hart and his crew of beachcombers of the trading cutter Lampton from Sydney, Australia, massacred as many as 50 Sapwuahfik men.
When they arrived, Sapwuahfik warriors were waiting for him on the coast, so Hart took Lampton to another islet of the atoll overnight.
The following day, Hart and his crew stormed the island along with two canoes of Pohnpeians who followed Lampton in tow.
[1] Two years following the massacre, Hart was investigated for the incidents by Commander P. L. Blake of HMS Larne.
