Question

How might the axis have benefited by gaining control of Great Britain in 1942.

Answer 1

If the axis powers took control of Germany during WWII then Germany wouldn't have to focus on Great Britain as much and could have focused more east and on the United States.   

Answer 2

The Axis would have taken Britain under control in controlling the Atlantic Ocean.

Step-by-step explanation:

If the Axis power (Germany, Rome, Japan) had gained control over Great Britain in 1942 in World War II, the history of Europe would have changed. By capturing Britain, German would have made the country as its military base to attack America. Which ultimately seize control over the Atlantic Ocean.

Germans were very much advance when it came to fighting in oceans. Battles in the Atlantic Ocean largely supported the Germans because of their U boats. They used their submarines to find Allied ships and sunk them with torpedoes.
