Soroca IasiCrossing the Dniester River between the Ukraine and Bessarabia had to be done by boat, that is why most Jews fleeing Russia at the turn of the century (19th-20th) went the northern route through Warsaw. The Cossacks were the primary enforcers of the "stay at home" policy of the Czar. They were (and are) ethnic Ukrainians.
Meyer and Ephraim narrowly missed being captured by Cossacks outside of Yampol in one of the many episodes of their journey through Europe. While Bessarabia (now Moldava) was under Russian control, the "enforcers" were the Russian Army and the police-both easily bribed or avoided through devious means, including false papers.
After near capture they were assisted by a boatman to cross the Dniester to Soroca. As the small boat approached the town the white fortress came into view.

Meyer and Ephraim rode from Soroca to Beltsi on a wagon, thus avoiding the Spring mud that they faced when on foot. Arriving in Beltsi, they were given sanctuary at a Romanian Orthodox church.
