Pretty turn on horseback

[sasibhaskar]

“Frightened me?" Rosas repeated. "Me, who've tamed horses in the South and then tamed an entire country?"
For the first time, Quiroga smiled.
"I know," he slowly said, "from the impartial testimony of your peons and seconds-in-command, that you did more than one pretty turn on horseback, but back in those days, across the Americas—and on horseback, too—other pretty turns were done in places named Chacabuco and Junin and Palma Redondo and Caseros.”

The above passage is from the book “Collected Fictions” by Jorge Luis Borges. I just wanted to know what it means by the sentence/words in bold. Could anyone help me out with this?

Thank you.

He did something impressive. Look at it that way. It says he did something impressive.

Does that fit with the rest of it?

There are a few ways of wording this but that's not one of them.

I wanted to know what the bold sentence means.
I wanted to know what the words in bold mean.
I wanted to know what is meant by the words/sentence in bold.
I wanted to know what the author means/meant by the words/sentence in bold.

Now give me your answer.

You appear to have omitted one very important word in that sentence.
