From a British 1944 report I was able to obtain map coordinates for some of the locations of Japanese buildings and facilities at Pengerang. The general Pengerang area was reported as to have been a hot bed for Japanese activity. It was thought much of the original British military facilities at Pengerang were simply re used by the Japanese, including the 6" gun emplacements.

The 1944 British report also noted a new operations bunker on the west side of Bukit Pengerang.

The report surmised that “bombs of considerable weight” would be needed for its reduction.
