 To " break the will of their domestic opponents and reaffirm their autonomy vis @-@ à @-@ vis their foreign allies " hundreds of pro @-@ Soviet , party moderates , military officers , and intelligentsia were arrested on 27 July 1967 , during what came to be called the Revisionist Anti @-@ Party Affair . All of the arrests were based on the individual 's stance on the Politburo 's choice of tactics and strategy for the proposed General Offensive . This move cemented the position of the militants as Hanoi 's strategy : The rejection of negotiations , the abandonment of protracted warfare , and the focus on the offensive in the towns and cities of South Vietnam . More arrests followed in November and December .
