Anybody know these answers ???

False, True, False, True

Explanation:

The first one is false because the union has 105000 soldiers and lost 23000, not 60% of that which is 63000.

The second one is true because Stone Wall Jackson was shot by his own men while he was on his horse two months before the battle happened.

The third one wouldn't make sense at all. The battle happened because Lee wanted to get some leverage in the north by forcing Northern politicians to stop prosecuting the war.

The fourth one is true. The confederates lost almost 40% of their men on that side and had to stop the advance because the battle wasn't going towards their favour.
