Warning; This is not to be taken seriously, and the degree by which humans win (spoilers) has been amplified for the purpose of comedy.
Have you been reading a 'Human/Pony War' fic and been wondering how the ponies are putting up a fight with medieval level weapons and magic, while we have firearms, nuclear weapons, armies the size of their entire population and most importantly, years and years of perfecting the art of war. This is how an actual human/pony war would go.... with comedy.

NEW PRINCESS ATTACKS GRIFFONSTAN IMPORTS

The Equestria Daily can exclusively report that newly crowned Princess Twilight Sparkle became embroiled in an argument with the Griffonstani trade minister about the inferior quality of griffon quills, alleging that "they just don't hold ink as well as pegasus quills". Import markets tumbled overnight, threatening the solvency of numerous Equestrian quill merchants. Princess Sparkle could not be reached for comment.

(When you're done, bookplayer has a fun "Let's Read" commentary version!)
(Also, GhostOfHeraclitus wrote a prequel from the perspective of Dr. Spinning Top!)
(Also also, now available in Spanish thanks to Spaniard-Kiwi!)

Her Royal Highness, Princess Luna, is trying to catch up on lost sleep. She deserves it, after all the hard work she's put in to keep the city of Canterlot safe. Now she can turn the lights down, slip into bed, and finally get some rest.

If only Canterlot weren't under attack by the endless swarms of the Changeling army...

Princess Celestia always knew that Twilight Sparkle was destined for great things, but she never revealed the source of that knowledge, not even to those closest to her. When the day of Twilight's true destiny finally arrives, can Celestia fulfill an ancient promise to save Equestia's past, present, and future, even it means saying goodbye to Twilight forever? How can Celestia refuse her mother's last wish?

Five years have passed since the events of that fateful morning. Smarty Pants and her friends set off on an adventure of a lifetime to discover the secrets of the past when they awaken a… oh wait, that would be spoiling it!

In response to threats of a griffon attack on Equestria, Twilight responds with a letter detailing just why such actions would prove unfavorable for them.

Today is Princess Twilight Sparkle’s 500th birthday, and her most faithful student, an earth pony with a familiar name, can’t wait to celebrate!

It is a little-known fact that all living beings are born with a finite amount of bucks to give. It is little-know due to the fact that most ponies will die long before all of their bucks could been given. But Twilight Sparkle seems to give a buck about everything, and she's depleting her storage far too quickly. This is what happens when Twilight Sparkle runs out of bucks.

Princess Celestia has been keeping a dark secret from her subjects for a very long time.

It's not an easy truth to tell, but if anyone can accept her after learning it, it will surely be her most faithful student.
