what happend in Africa and Europe that caused Germany to withdraw all of it's might from attacking England?

Germany got involved in wars with the Soviet Union (eastern front), and faced oposition in Northern Africa from the Allies, especially in Libya and Egypt. As a result, Germany had to abandon its idea of invading England, and instead, focused its efforts in the Soviet Union and Northern Africa.

Explanation:

By 1941, Germany had launched the Operation Barbarossa, whose goal was to defeat the Soviet Union, slaughter a bit part of its population, and repopulate the Soviet Lands with German subjects. While at first, this operation was a success, it soon became a nightmare for the nazis, because the Soviet resistance was fierce and began to push back.

In Africa, Germany also faced opposition, especially in Egypt, which was a British colony, and neighboring Libya. One of the most famous Germans Generals: Erwin Rommel, was defeated there.
