Interesting. I do know that 4 Chabad Chassidim were beaten to death by misnagdim in sventzian (see the making of Chassidim). The Berditchover and R shmelke and others were also majorly persecuted.
There were no retaliations as far as I know. In fact, the Alter Rebbe famously wrote about not even whistling back after he was released (he was put in jail by misnagdim.)
