Labrador battery is one of the surviving gun emplacements in Singapore today. In 1878, the British built an artillery fort on this ridge in preparation for seaward attacks. Such a defence was not planned for the northern shores of Singapore as the north was protected by the mainland of Malaya and the northeast by the fortified Naval Base.
The battery boasted two 6-inch guns, positioned to face south. However, contrary to popular belief, these gun were swung around to fire at the approaching Japanese troops along Pasir Panjang Road. Weighing 16 tons each, they had a range of over 10 miles and could fire a 102-pound shell with a 31-pound cartridge.
Labrador Park was one of the prepared defensive positions. In the Battle for Pasir Panjang, these guns aided the Malay Regiment by firing high explosive shells at enemy troops advancing along the coastal road. Tunnels and bunkers beneath the Battery were used to supply ammunition and included living quarters for troops.
The Japanese found the two guns operational upon occupying Singapore. However, the barrels were badly rusted and the breech-blocks in need of repair.
