While the ponies were celebrating for their victory in the Great Plains and in Hoofington, in Ponyville it was much different. The Royal Guards have a hard time defending Ponyville because it's big, and it might overstretch their defenses too much. Ponyville is a town near Canterlot, and it's strategically important because of it's railroad tracks, and also houses the Elemental Bearers of Harmony. Out of them though, Fluttershy is the most vulnerable to Griffon attack, but the Royal Guards are still debating whether or not to go out there, thinning the line even more.
For the Griffons, unaware that the line is thinning, hatch a bold and decisive plan to have another victory after two defeats in a row. Their plan, is to attack south from Applejack's orchards and the Everfree Forest simultaneously, kill all of the Guards there, and capture the city. The Elements of Harmony are scattered along Ponyville, making it difficult for the guards to defend them all.
But Ponyville will be adequately defended by something out of the ordinary.
>Attack Begins<
At the twelve o'clock, the Griffons charged at the thinly defended line that will safeguard Ponyville. At the western attack, the Griffons must first probe Equestrian Lines, now defended by the American 180th Tank Destroyer Battalion. With them is the 34th Royal Guards Division, extremely nervous with the Tank Destroyers. Their commander, Dexter, is having the nerve.
"Sir?" One of his soldiers asked.
"What is it soldier?" But before the soldier that was asking him could reply, a loud cry was heard, and that sound was something that the Equestrians dread about. That is the indication of a Griffon attack. But when Commander Dexter notice the TD's, they were completely calm, no indication of fear or whatever. The Griffons advanced, and the ponies readied themselves for an impending battle. However, when the Griffons are now a thousand yards away, a boom was heard, and when the ponies look around, they could see one of the Tank Destroyers have fired.
The M36 'Jackson' is one of America's tank destroyers built during World War II. It is protected by 4.25(or 4.3) inches of frontal armor, but it's most deadly feature is it's powerful 90 mm Main Gun, capable of knocking out several griffons. The M36 Tank Destroyers fired their main guns, raining havoc across the attacking Griffons. The ponies were not believing this. This 'humans' that introduced themselves a while back to assist them, could not believe that they are capable like this. The Griffons are now thinning, tries to throw on the ranks of both humans and ponies.
But the spears just broke in two, like it was nothing, in the armor of the American Tank Destroyers. The ponies are now confused as in how in Tartarus could these 'humans' shrug off spear attacks. But even with that, the Jackson's continue firing their gun, killing other Griffons caught on the crossfire.
While the western line was having their own battle, the eastern line was also having their own battle. With the 78th Royal Guards Division is the 45th American Tank Battalion. The 78th's commander, Alloy, is now getting nervous, with his soldiers, when the Griffon war cry was heard, but for the Americans, it's nothing. The Griffons, like their western counterparts, are now advancing at terrifying speeds, getting the ponies scared to death. But then, a boom was heard in the eastern line, and the Americans fired their tanks at the advancing Griffons.
The M4A3E8 Sherman is a variant of the famous Allied tank. With a 76 mm Main Gun, it's a deadly killing machine like the M36 Jackson. The Sherman's fired their main guns at the Griffons, killing several at the process. Now, the Americans fire their machine guns at the Griffons, killing them effectively in a hail of gun fire. With both Griffon division down, the ponies thought that it was over, but it was not. Hovering towards the line is the Mark III Zeppelins, the Griffons 'flying machine'.
The Mark III Zeppelin is a blimp designed to rain down arrow fire, making it a deadly foe to the Equestrians. The ponies spotted the the zeppelins, and they are now cringing in fear. However, noises are coming in from the south, and to their shock, another group of 'flying machines' are now flying, this time towards the zeppelin group. With that as a signal, the Americans advance forward, trying to meet up with the other tankers at their meeting point. The 'flying machines' fired their arrows.
The P-51 Mustang was the standard aircraft of the United States Air Force. Armed with six .50 caliber Browning machine guns, it is truly a deadly foe. The P-51 Squadron fire their machine guns at the zeppelins, who in turn fire back with arrows. However, it was not effective as the zeppelins goes out one by one, and in a few minutes later, they were defeated. With their victory, the last of the Americans goes to the south, leaving the ponies with the victory. And with that victory, the Griffon juggernaut is now at a halt. This is the time that the ponies will regain their lost lands from the Griffons.
