Read Grant’s memoirs. He was a very good writer, and the story is enjoyable. It only takes a few hours to read.
Grant wrote them as he was dying from throat cancer so his wife would have money. They were published by Mark Twain.

“He was a very good writer, “
Dude, he didn’t write them!
You REALLY should not post fake news.
“...so his wife would have money.”

And Grant succeeded. His two-volume autobiography was a best seller and made his family a great deal of money.
I have one volume of the original set from the 1880’s in mint condition. I will eventually find it’s companion volume.
At the time there was no presidential pension and no Secret Service protection.
That came later.
