Q: Information: - The Battle of the Atlantic was the longest continuous military campaign in World War II, running from 1939 to the defeat of Germany in 1945. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. It was at its height from mid-1940 through to the end of 1943. The Battle of the Atlantic pitted U-boats and other warships of the "Kriegsmarine" (German navy) and aircraft of the "Luftwaffe" (German Air Force) against the Royal Canadian Navy, Royal Navy, the United States Navy, and Allied merchant shipping. The convoys, coming mainly from North America and predominantly going to the United Kingdom and the Soviet Union, were protected for the most part by the British and Canadian navies and air forces. These forces were aided by ships and aircraft of the United States from September 13, 1941. The Germans were joined by submarines of the Italian Royal Navy ("Regia Marina") after their Axis ally Italy entered the war on June 10, 1940. - A merchant aircraft carrier (also known as a MAC) was a limited purpose aircraft carrier built on a British hull designed for bulk grain ships and oil tankers. This was adapted by adding a flight deck enabling it to operate anti-submarine aircraft in support of Allied convoys during the Battle of the Atlantic during World War II. - World WarII (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World WarII the deadliest conflict in human history. - MV Empire MacKendrick was a grain ship converted to become a Merchant Aircraft Carrier or MAC ship .

He was first to make Polotsk autonomous from the Grand Duke of Kiev passing his title to his descendants after his death . His principality carried a wide degree of autonomy that later was passed and to his descendants as well . His glory was commemorated after an established city that was named after him . Izyaslav died at the young age of about 23 , in 1001 , surviving his mother but predeceasing his father Vladimir of Kiev , thus excluding his descendants from ever succeeding the Kievan throne , according to the so - called '' ladder succession '' . The name of Izyaslav 's spouse is unknown . He had two sons : Bryachislav of Polotsk and Vseslav . Both were certainly minor at the time of his father 's death .
