 On June 2, 1940, Germany informed the Romanian government that, in order to receive territorial guarantees, Romania should consider negotiations with the Soviet Union.From June 14–17, 1940, the Soviet Union gave ultimatum notes to, Lithuania, Estonia, and Latvia, and when these ultimata were satisfied, used bases thus gained to occupy these territories.France's surrender on June 22 and the subsequent British retreat from Europe rendered their assurances of assistance to Romania meaningless.
