Why does the narrator in the story “the pioneer hep-cat” tell the story of general henry t. corrigan?

I believe the answer is: because the narrator want to highlight 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

The narrator pointed out that Despite his immense success in climbing up millitary rank, General Henry T. Corrigan's personality still hasn't change ever since he was a kid. He still enthustiastic in meeting people from his childhood and showing them kindness.
