Soviets attack Mannerheim Line
Thursday, February 1, 1940 www.onwar.com
Anti-tank traps of the Manneheim LineThe Winter War... The Soviets initiate attacks against the Mannerheim Line, especially in the Summa area. There is an extensive preliminary bombardment to add to the artillery efforts of the past two weeks. The Soviet 7th and 13th Armies have 14 divisions and six tank brigades in the advance, with strong reserves. The Finnish 3rd Division, holding the line in the Summa area, takes much of the weight. During this round of attacks (which continues until February 8th) there is no attempt at a breakthrough by the Soviets but almost continuous heavy pressure is maintained.
In Tokyo... A record budget is presented to the Japanese Diet. Almost half is to be devoted to military expenditure. Meanwhile, Japan makes a diplomatic protest to Britain concerning the removal of 21 German nationals from the liner Asama Maru by British forces of the HMS Gloucester and demands they be returned. (The Asama Maru incident of January 21st.)
From Yenan... The Chinese Communist Mao Tse-tung calls for the US to stand firm against Japan.
Mao sure had a funny way of thanking us for the favor we did.
