About the interest of the current project in English class

We had project about all kind of stuff.
Two week was given to the students.
We formed three people in one group and divides 50 question.
While I was researching, I was very surprise at the facts that over 55million people died during WWII. And the Russia lost most of the people, close to half of the 55 million.
It was same as when Napoleon try to invade Russia.
The time was winter and soldiers are not ready for the cold winter but Russian army was.
So Napoleon had to give up. As Napoleon didn't thought of the whether, Hitler did not care about the whether and lost hundreds of the soldiers and retreat.
Many died on the land of the Russians.
