On June 26, 1940 the Soviet government issued an ultimatum to the Romanian minister in Moscow, demanding Romania immediately cede Bessarabia and Northern Bukovina. Italy and Germany, which needed a stable Romania and access to its oil fields urged King Carol II to do so. Under duress, with no prospect of aid from France or Britain, Carol complied. On June 28, Soviet troops crossed the Dniester and occupied Bessarabia, Northern Bukovina, and the Hertza region.
