 The Soviets transferred Wilno to Lithuania according to the Soviet–Lithuanian Mutual Assistance Treaty.Lithuanian troops entered the city on 27–28 October.The defence of Wilno has been criticized by some Polish historians, who point out that if properly organized, the Polish forces would have been able to hold on to Wilno and delay the Soviets by several days, similar to the defence of Grodno (in which some of the units which withdrew from Wilno took part).
