Reb Yeruchom Gives Rav Chatzkel Levenstein Advice In The Dark Of Night
Rav Chatzkel Levenstein z’tl was the mashgiach of the Mir Yeshivah during WWII, when the entire yeshivah escaped to Shanghai.  Rav Chatzkel spoke constantly about emunah and bitachon, which was so necessary during that difficult and frightening time.  He taught the talmidim to feel a palpable sense of emunah and bitachon at every moment. 

At one point during the yeshivah’s sojourn in Shanghai, the city was being heavily bombed.  It was suggested that the yeshivah leave the city and move to a town called Charvin. R’ Chatzkel opposed the move.  Later, R’ Chatzkel revealed that R’ Yeruchom Levovitz, his predecessor, had appeared to him in a dream, and spoke against the move. 

The yeshivah stayed in Shanghai, despite the great danger, and the promise of a safer haven in Charvin.  When that period of danger had passed, the yeshivah heard the news that Charvin had been bombed twice as much as Shanghai, and the city had suffered countless casualties.  (R’ Yaakov Finklestein, former Mir talmid)
