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 War II (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 War II the deadliest conflict in human history.  - MV Empire MacKendrick was a grain ship converted to become a Merchant Aircraft Carrier or MAC ship .

Q: Information:  - The Eclogues ( / klz / ; Latin : Eclogae ( klaj ) ) , also called the Bucolics , is the first of the three major works of the Latin poet Virgil .  - The Georgics is a poem by Latin poet Virgil, likely published in 29 BC. As the name suggests (from the Greek word , "gergika", i.e. "agricultural (things)") the subject of the poem is agriculture; but far from being an example of peaceful rural poetry, it is a work characterized by tensions in both theme and purpose.  - The Appendix Vergiliana is a collection of poems traditionally ascribed as juvenilia of Virgil, although it is likely that all the pieces are in fact spurious. Many were considered works of Virgil in antiquity, but it seems that they comprise a diverse collection of minor poems by various authors from the 1st century AD.  - Publius Vergilius Maro (traditional dates October 15, 70 BC  September 21, 19 BC), usually called Virgil or Vergil in English, was an ancient Roman poet of the Augustan period. He is known for three acclaimed works of Latin literature, the "Eclogues" (or "Bucolics"), the "Georgics", and the epic "Aeneid". A number of minor poems, collected in the "Appendix Vergiliana", are sometimes attributed to him.  - Latin literature includes the essays, histories, poems, plays, and other writings written in the Latin language. Beginning around the 3rd century BC, it took two centuries to become a dominant literature of ancient Rome, with many educated Romans still reading and writing in Ancient Greek, as late as Marcus Aurelius (121180 AD). Latin literature was in many ways a continuation of Greek literature, using many of the same forms.  - The Aeneid is a Latin epic poem, written by Virgil between 29 and 19 BC, that tells the legendary story of Aeneas, a Trojan who travelled to Italy, where he became the ancestor of the Romans. It comprises 9,896 lines in dactylic hexameter. The first six of the poem's twelve books tell the story of Aeneas's wanderings from Troy to Italy, and the poem's second half tells of the Trojans' ultimately victorious war upon the Latins, under whose name Aeneas and his Trojan followers are destined to be subsumed.
