Said Abu Bakar was an Acehnese religious teacher at Kampung Aceh in Yan, Kedah, known for his piety and often addressed as ‘Tuan Sheikh Abu Bakar’. In early 1942 he became the most important link between the Acehnese émigré network and the Japanese intelligence unit Fujiwara Kikan, and then led two groups of agents who infiltrated Sumatra. His authority as an ulama made Japanese propaganda acceptable in Indrapuri, Seulimeum, Piyeueng and Aceh’s west coast. His name has almost vanished from the official Japanese military narrative, although field commanders implicitly acknowledged his role.
