After the 1963 Policlinico Bancario assault and the 1964 murder of Raúl Alterman, many MNTers were arrested or forced into hiding. Thus, in the same month, March 1964, the two rival branches of Tacuaras (MNRT and MNR), were disbanded. The group was officially outlawed in 1965 under president Arturo Illia (UCR). After having met Perón, fighting in Vietnam (against the US) and travelling to China, Joe Baxter, one of the founders of the MNT, turned toward the revolutionary left-wing and finally became one of the cofounders of the ERP, alongside Mario Roberto Santucho. Baxter died on 11 July 1973 in a plane crash in France.
