since the end of world war ii, the grave of rebbe nachman, in the city of uman, ukraine, had been an impossible to reach goal for breslovers living outside the soviet union. the soviets had turned the city into a closed military zone that was off-limits to foreign visitors. with the help of a travel agent who had connections to soviet chairman nikita khrushchev, rosenfeld led the first official group of american breslovers to uman in december 1963. he returned with other groups of students in 1966 and 1967, and visited the grave another 13 times before his death. uman was eventually opened to foreigners after the fall of communism in 1989.
