not bad, but like before you have some errors.
1- correct me if I'm wrong but isn't Blackthorn city in Johto? and even if you knew that then why would they attack it when they want Kanto?
2- you have a lot of typos and spelling mistakes
3- some grammatical issues and words that don't exist like "unflyable" try "grounded"
I suggest you revise the chapter find those mistakes and correct them such as: Shortley-shortly, rulur-ruler, missle-missile.....
best of luck
