The Port Hamilton Incident or the Geomun Island Incident was the occupation of the Port Hamilton (also Komundo or Geomundo) by the Royal Navy from 15 April 1885 to 27 February 1887. Russia had intended to use the island as a coaling station. Russia threatened to occupy parts of Korea, in response to British actions. After giving assurances they would not occupy any part of Korea then the British withdrew. The proposal to occupy the islands had been considered earlier by the British Cabinet, in July 1875, but was rejected by Foreign Secretary Lord Derby as setting a poor precedent.
