Term
Atlantic Charter
Definition
August 14, 1941 - Newfoundland

Franklin Roosevelt and Winston Churchill met on a battleship to discuss what they believed to be common hopes for a better future. This consisted of acting in the interest of all people and preserving the right for said people to choose their own governnment. They would also act to restore sovereignty to those nations who'd lost it along with their government. This was somewhat of an awkward agreement as two of the three "big three" leaders had no intention in following these principles. Moreover, Roosevelt expressed at this time to Churchill that he would find an "incident" to enter the war - which would be Pearl Harbor.
Term
Battle of Britain
Definition
June 1940 – April 1941

After the German Army defeated French at Dunkirk, they sought out Britain. Hitler attempted to form a German-British alliance, but Churchill refused. In July of 1940 Hitler planned an invasion of Britain for September 15. He sent the Luftwaffe to destroy air & naval forces. Germany made the mistake of focusing bombing on cities - which was unsuccessful. The RAF was stronger than they thought/ Hitler hadn't achieved any of his objectives so he decided to scrap the idea and focus mainly on the Soviet Union. If the RAF hadn't been successful, Operation Sealion would have been executed and Germany could've won the war.
Term
Battle of Guadalcanal
Definition
August 1942 to February 1943

By 1942, Japan had control of vast territory due to their "miraculous six months" of ruthess conquest after the bombing of Pearl Harbor. Japan looked to new naval bases in New-Guinea where it could attack Australia. The tide of the war turned though. The Battle of Coral Sea in May 1942 and the Battle of Midway in Jule, however, stopped this from happening. The naval forces divided the Pacific into three regions under Admiral Nimitz, Admiral Halsey, and General Douglas MacArthur. They planned to use island hopping in order to achieve allied victory. Nimitz was in charge  of the central Pacific islands. He launched his attack on the Solomon islands in August 1942. The battle lasted six months and was costly despite allied victory.
Term

Battle of Okinawa

The last German offensive mounted on the Western Front. Bulge refers to the bulge put in the allied line of advancement. The goal was to split the allied line in two, capture Antwerp, Belgium, and then surround the allied armies. The idea was to force the allies into negotiating a peace treaty. Under Dwight D.

Germany lost a large portion of their military and much of their air force was destroyed.

El Alamein
Definition
June – July 1942

Axis and allied forces chased each other over North African desert for years. The tide turned in the allies' favor at the Battle of El Alamein in 1942. General Montgomery who was pushed out of Libya and back to El Alamein spent months building up men and amor before launching an attack on Rommel. Because Rommel drove the allies out of Libya, the axis used all their food and supples and ammunition so they could advance no further. This allowed for an allied invasion known as Operation Torch to attack Rommel's army from behind. This was a major allied victory and a turning point in the war.

Term
Hiroshima / Nagasaki
Definition
Hiroshima and Nagasaki were Japanese cities that were destroyed by the atom bombs developed by the United States. The first atomic bomb (Little Boy) was dropped on Hiroshima August 6, 1945 – and three days later Fat Man was dropped on Nagasaki.

The use of the bomb was – and still is – extremely controversial. Norman Rich outlines a number of reasons why this was so; American leaders knew that the use of the bomb wasn’t necessary to win the war; they could have continued mass bombings via “conventional weapons” or set up naval blockades to cut off the food supply to the Japanese – whose vitality depended on imports. They could have waited until the entry of the Red Army – or they could have carried out the plan to attack the home islands. One such opponent of using the bomb was general Douglas MacArthur who publicly criticized Truman’s decision to use the bomb.

However, when Harry S Truman found out that the atom bomb was fully operational at the Potsdam conference, the overriding decision was to end the war as quickly as possible and to save American lives. This news meant that the last island hop was unnecessary. Historians, however, still question why the decision was made to bomb Nagasaki only three days later, when the Japanese had no chance to fully absorb the effects of Hiroshima.
Term
Island Hopping
Definition
The concept of Island Hopping was coined during World War II to describe the Allied attack and hope to gain control of Japan. Instead of going after mainland Japan first, the Allies, mostly made up of American troops, engaged in a series of battles on smaller islands in the Pacific. This strategy by the Allies was called leapfrogging
Term
Maginot Line
Definition
A massive fortification that was created on France's German border, starting at the Ardennes Forest and spanning across Alsace & Lorraine. IT was created in the 1930's to prevent another German offensive from invading France. However, blitzkrieg destroyed it which split the French border by going around the Maginot Line forcing the French soldiers to Dunkirk sparking the idea of Operation Sealion.
Term
Neutrality Laws / Lend-Lease Act
Definition
1935, '36, '37, & '39 neutrality laws forbade the sale of arms to countries involved in war. These laws were staunchly defended by isolationists. The U.S. then allowed Britain to purchase on a cash-carry basis which eventually led to the Lend-Lease Act of 1941 that extended aid to the Soviets.

Battle of Midway
Definition

Six months after the Japanese bombed Pearl Harbor and about a month after the Battle of Coral Sea, the American Navy spoiled the Japanese’s attempt at conquering Midway Atoll. Japan was intending to eliminate the U.S. as a power from the Pacific region. This is why the Battle of Midway is considered one of, if not the, most important battle in the Pacific. The U.S. was able to deliver a crippling blow because of the American code breakers who intercepted a signal and became aware of the date and location of the so-called ambush. This weakened the Japanese Imperial Navy and allowed future victories for the U.S. to arise known as Island Hopping.
