What was the duration of the war that was in progress when the USS McAnn first served in the Atlantic Ocean?
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 countries—including all of the great powers—eventually 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.
Siege of Boston The Siege of Boston (April 19, 1775 – March 17, 1776) was the opening phase of the American Revolutionary War. New England militiamen prevented the movement by land of the British Army garrisoned in what was then the peninsular city of Boston, Massachusetts. Both sides had to deal with resource supply and personnel issues over the course of the siege. British resupply and reinforcement activities were limited to sea access. After eleven months of the siege, the British abandoned Boston by sailing to Nova Scotia.
