Preston Garvey knelt down to tend to one of the many wounded Minuteman soldiers that littered the ground of the Castle courtyard. This particular Minuteman had major burns on his both of his shoulders, but his leather armor had been destroyed in the previous battles. Preston bandaged the wounds to try to keep an infection out from starting. "Thank you, sir." The Minuteman said has he struggled to move to look up at him.
Preston simply nodded and got up and took in the sight, Minuteman troops patrolled the walls while their medic forces attempted to save the many Minuteman that had been injured. Looking at the sight made Preston realize how much he truly hated the Institute. The Minuteman had never bothered them, they were just trying to help the people of the Commonwealth, but the Institute had attacked them. Even now nearly an hour after the battle had concluded Minuteman artillery kept the Synths that were still attempting to breach the walls contained. A set of heavy footsteps made Preston look up.
"Preston, I want you to take your squad and get back on the northern wall, the bastards are preparing for another attack." General John Pershing, the Sole Survivor of Vault 111, started. "We don't have the artillery shells to keep the barrage and when we quit the Institute's going to hut us with everything they have here."
Preston nodded and asked "Has Lewis been able to get back into contact with the any of our settlements?"
Pershing nodded his head and said "No, but we have to keep our thoughts here. If were defeated here then the rest of the settlements won't have a hope of defeating these bastards."
Preston had to agree with that. The different settlements alone didn't have the manpower or the will to fight against the Institute without the protection that the Minuteman provided. But Preston had to put thoughts like that out of his head, they had a battle here and now that needed winning. He looked over to his squad who were sitting against the stairs that lead up to the defensive positions.
One of the soldiers who were standing up looked at him and asked "What's the plan Colonel?"
"Were moving to support our men on the northern wall, the Institute going to hit us soon and we need to be prepared for anything."
A few moments later, Preston and the squad were on the wall and looking towards the city ruins. The artillery bombardment continued but was beginning to slow down. Preston knew that the coming hours would either see the Minuteman emerge victorious, or they would fall apart for the second time in a single year. Preston faintly heard The General give the order for the artillery to stop firing. Preston swallowed and the firing stopped and then all hell broke loose.
The Synths launched themselves from their positions in the city, as the Institute also relayed in synths closer to the Castle walls. "Open Fire!" Preston yelled and fire, both ballistic and laser erupted from the walls of the castle. Several of the synths fell as the fire overwhelmed them, but the synths kept coming. Preston cranked two more rounds into his Laser Musket and fired into the crowd. The fighting continued like this for several more moments, before in another flash blue appeared, but this time much closer. The Institute had relayed synths onto the walls of the Castle itself. Preston turned and fired into one of the synths who had just rematerialized. The Minuteman who had been focused on the battle going on outside the walls shifted their fire to the fight that was now taking place across the courtyard and the top of the walls. Preston took a moment to survey the battle taking place in the rest of the Castle. The Institute had overrun the western wall, and the Minutemen who had been defending the wall had been forced onto the courtyard and were slowly being picked off by the Synths. Luckily the eastern walls had not fallen to the Institute, and the Minutemen stationed there had begun attacking the synths. Preston smiled, for a second there he had thought they had had lost the battle, but there was still hope.
General John Pershing was not feeling hopeful about the situation at hand. The Institute was pushing hard on the western walls, and Preston and his men were still in a fight for their lives on the northern wall. Ronnie Shaw was leading the charge from the eastern walls, and Danse was with him. Despite the setbacks, he was not willingly to let the Institute to have the Commonwealth however. John looked back to the battle at hand, the Institute had taken the northern wall, and he and Danse were trying to plug the hole in their defenses. He had just taken a shot with his R91 Assault Rifle when he heard it. Rotor blades which belonged to Vertibirdd, and there was only one faction that had access to that kind of pre war tech. John looked up and saw five Vertibirds dropping down towards the Castle, one of the vertibirds swung around to reveal its minigun as it opened up on the western wall, Powered Armored soldiers dropped from the other across the entire battlefield. It was then that John remembered that Danse was a synth and what the Brotherhood thought about synths.
"Danse!" Danse looked over as John continued "Here out this gas mask on!" the gas mask was one of the things that John always had on him, and today he was happy that he had it. Danse nodded his head in understanding and put it on quickly.
The General looked back at the battle, the Brotherhood had appeared to swing things back in the Minutemen's favor. And he smiled despite himself, the Institute was going to pay for what they had done to the Commonwealth, and for what they had done to him personally.
The fight was still not over yet. And John knew that. He ordered for the men that had been forced down the western walls to follow him as he charged up the stairs, straight into the Institute synths. John fired blindly into anything that resembled a synth. The fighting was intense and bloody, but the Minuteman charge succeeded and threw the Institute off of the walls. After which the Brotherhood vertibirds fired on the synths that were retreating. The Battle of the Castle was over, and the Minuteman had just won a surprise victory against the Commonwealth's boogeyman. And now John had to find the leader of Brotherhood force and figure out what they were going to do next.
