Lei Yue Mun (Carp Gate), half-hidden
at the right, is the harbour’s eastern entrance. Set below Devil’s Peak,
a flat-topped knoll with defensive emplacements, Lei Yue Mun is — at its narrowest — barely 500 metres wide. Strong tides can rip through the channel, making negotiating it difficult. The denuded hills are the result of shelling onto Japanese positions in December 1941, before their landing on the Island.
