This book offers an in-depth look into the personal diaries of Alexander Rankin Johnstone Dunlop, a British officer with the British North Borneo Company from 1885 to 1915. Spanning the years 1897 to 1901, the diaries capture the challenging and often perilous journey of early Company rule in Sabah, focusing especially on the relentless pursuit of the notorious rebel leader, Mat Salleh, who led an uprising against the Company from 1894 to 1900.
