 As a consequence, Soewardi was arrested under the order of Governor General Idenburg, and sentenced to exile in Bangka Island.However, both his colleagues, Douwes Dekker and Tjipto Mangoenkoesoemo, protested on his behalf, and eventually in 1913, the three of them were exiled to the Netherlands instead.These three pro-independence activist figures, Soewardi, Douwes Dekker and Tjipto, were later known as the "Tiga Serangkai" or the "triad".
