Named after the American brigade general Richard C. Drum (1825-1909). The fortress was built between April 1909 and 1916 on the island El Fraile, Philippines as part of defence line which blockaded the entrance to the Bay of Manila. First intention was to use Fort Drum as a mine control and mine casemate station but then to make a real fortification of it. This was accomplished by building a concrete made structure above the island fitted out with x-14”/36cm guns placed in armoured rotating turrets to which 2x2-6”/15cm guns in armoured casemates and 2-3”/7,6cm mobile anti aircraft guns were added. Fort Drum was involved in the Second World War and finally handed over to the Japanese. In April 1945 was she recaptured by the American forces but damaged beyond repairs was the fort taken out of service.
