An anecdote about of "The Little Match Girl"

There is an anecdote about of "The Little Match Girl". The little match girl is a real character in Andersen’s life.

Summary:
One autumn evening in Copenhagen, Denmark, H.C. Andersen, an author, accidentally met a poor little girl selling matches in the street. She was afraid to go home because she hadn't she sold any matches, and her father would beat her if she didn't sell anything [not perfect but future conditional with modal verb of possibility]. H.C. Andersen gave her all of his money. He would travel somewhere leave in the next few days, so he promised her he would give her some other gifts when he comes back [to travel somewhere has the connotation of going towards something not away]. The little girl also promised to give him a gift.

When Andersen had come came back to the city, he remembered his promise. He brought [bought = buy, brought = bring] sweaters and a fleece jacket for the little girl. After asking around about the little match girl, he found out that she froze to death one cold winter night, and there was a pen-holder with text, “For Mr. Andersen” in her pocket [using "knew' gives the sense that he already knows]. She still remembered her promise.

"The Little Match Girl" is a present which author Andersen would like to dedicate to the little girl’s soul, isn't it?

The past perfect is used to connect something that happened in the past to the present. (I have walked for days just to get here.)

The simple past is used to talk about a single action that happened in the past. (He threw the ball.)
