The 4th Army was a Royal Yugoslav Army formation mobilised prior to the German-led invasion of the Kingdom of Yugoslavia during World War II. It initially consisted of three infantry divisions, one brigade-strength detachment, one horse cavalry regiment and one independent infantry regiment. It was responsible for defending a large section of the Yugoslav–Hungarian border, being deployed behind the Drava river between Varaždin and Slatina. Like all Yugoslav formations at the time, the 4th Army had serious deficiencies in both mobility and firepower, and it was only partially mobilised when the invasion began on 6 April 1941. The 4th Army put up scattered resistance, but began to withdraw southwards on 9 April, and on 10 April it ceased to exist as an operational formation. The remains of the 4th Army were ordered to stop fighting on 15 April, and the Yugoslav Supreme Command surrendered unconditionally, effective on 18 April.

___________________________ Wikiquote quote of the day:

From time immemorial to the present day, mankind has been looking for heroes. People always appreciate heroes. They always support those who are brave. And always feel who is fighting for the good. During the 50 days of this war, Ukraine became a hero for the whole free world. For those who have the courage to call a spade a spade. For those who are not poisoned by propaganda. You have all become heroes. All Ukrainian men and women who withstood and do not give up. And who will win. Who will return peace to Ukraine.   --Volodymyr Zelenskyy https://en.wikiquote.org/wiki/Volodymyr_Zelenskyy
