I just saw a hashgacha pratis story like this, a mother in London in the beginning of WWII heard of a Kindertransport by boat from England to the US, and thought it might be good idea for her children. But she would not do it without advice from a gadol. She asked a rabbi, but he said he needs to do Goral Hagra - a system from the Vilna Gaon of turning pages a certain way, and getting a message from a posuk on the page it ends up on, but he said he wants to fast before doing it, and has no strength right now. Several days went by, and then, even on the day of the boat's leaving, he still said he still has no strength. The boat left, and they soon found out that it had been bombed by the Germans, and many were killed.
