Details:

Germany and the Soviet Union had signed a mutual non-aggression pact in 1939, pledging not to go to war with one another for the next ten years.  But in 1941, Hitler broke his non-aggression pact with Stalin and invaded Soviet territory.  The German invasion ordered by Hitler was massive way, intending to secure a quick victory.  Germany  sent over 3 million soldiers, and 3,000 tanks were involved in the attack.  The German generals had predicted that they could win in 10 weeks' time.  As we know, that didn't happen, and the war on the Eastern front between Germany and the USSR became the bloodiest theater of war in World War II.

in his book, the riddle of the rosetta stone, james giblin talks about how there was a young british polymath and physician named thomas young who made a lot of advances on the deciphering of the rosetta stone. he says that even though young made a lot of mistakes because he was working under false assumptions, he also made huge contributions like deciphering three out of the seven symbols (more than anyone else before him). young published his findings and continued his good work but he wasn't able to progress much further due to some unfavorable situations, he still laid the basis for many other scholars and of course for the man who has been generally known to have deciphered it, jean-françois champollion
