"Secure the blessings of liberty, to ourselves and our prosperity"
Here is the full name list for this question:
<span>George McClellan
Henry Halleck
Joseph Hookker
George Meade
</span>????
I believe the answer is: <span>Ulysses S. Grant
All the name above are the generals who fought for the union side. From the name above, </span><span>Ulysses Simpson Grant probably held in highest regard due to his huge contribution in defeating the confederate army. As a reward, President Abraham Lincoln made him the commander of all the generals.</span>
