The article is devoted to the new historical research works on Polish reactions to the annexation of Klaipėda by Germany in 1939. Poland took into consideration the possibility of the German occupation of Klaipėda from the end 1938. The Foreign Minister J. Beck declared to the British ambassador in Warsaw H. Kennard that the government maintains a restrained attitude in case of a crisis caused by the issue of Klaipėda. Simultaneously, in interviews for the press, he categorically denied any possibility of Poland and German agreement at the expense of Lithuania. In spring and summer of 1939 the Polish government was very anxious to maintain good relationships with Lithuania. The policy of neutrality declared by Lithuania was received with great satisfaction.
