In 18 January 1939 the "Dobama Asiayone" declared its intention to use force in order to overturn the government, leading the authorities to crack down on the organization. On 23 January Police raided their headquarters at Shwedagon Pagoda, arrested Aung San, and held him in prison for fifteen days on charges of conspiracy to overthrow the government, but these charges were dropped. Upon his release Aung San proposed a strategy of pursuing Burmese independence by staging countrywide strikes, anti-tax drives, and guerrilla insurgency.
