The recent political debate on SOFA, MCC etc (see Roberts 2019) highlights the place of KOGGALA in the Western imperial map of the Indian and Pacific Oceans. The British airfields at Katunayake Trinco and Koggala were part of the imperial defence system – a geo-political ensemble that became even more significant after the fall of Singapore to the Japanese in WW Two marked vulnerabilities not envisaged till then.
As USA replaced Britain in the Western command of the world order and Britain lost access to Koggala and its other Ceylon assets, replacements became essential. Gan in the Maldives was quickly developed. The aboriginal peoples of the Chagos islands were evicted and dumped in other island colonies by the British in the early 1960s and the atoll isles handed over to USA for an air and sea base at Diego Garcia to be developed (see Ashley de Vos article in Thuppahi).
A FOOTNOTE: in the late 1950s our Galle gang (Audrey Roberts, Alastair & Trevor Roosmale-Cocq, Elmo de Alwis, Vidya and Lucky Wickremasinghe and myself) used to bike – a long haul this – to Koggala to (a) explore the deserted base and climb its control tower; and (b) swim in the seaside pool (which had been created by depth-charges blowing a space in the reef edging the shoreline). These were magical moments for young adventurers.
