The book offered to readers is dedicated to completely different operations of the Second World War: the occupation of Denmark and Norway in April - June 1940, battles in Southern Europe in 1940-1941, as well as combat operations in the North Caucasus in the spring of 1943. In three distant theaters of military operations, armies of different states fought each other. But still, there is one single principle that unites such dissimilar “battles of different nations” - these are air and sea landings that the warring parties carried out in the presented operations.
