It looks and sounds great to me!
I think the best answer is history. The story of the Trojan War is primarily an example mythology where the purpose is for history. Mythology was one means to describe the environment during the ancient times. Myths were used to re-tell historical events.
He was saying that despite being a famous Army Officer, General Corrigan was a man who never forgot where he came or the people he grew up with.

I believe the answer to question two is true. Political writings were usually persuasive.
Hope I helped!
