Diesel 10 was not reacclimating well. On his first night in service, he showed up at Vicarstown sheds.

"C-can w-we h-help y-you?" Arthur asked, stuttering like his shedmate Molly.

"Well, you certainly can," the Warship said, "I need a load."

He then coupled up to Arthur and began to pull him away. Immediately, police were called. The line from Barrow to Crovan's was shut down, and Gordon had his strongest and Fastest Engines carry SWAT teams. He himself took on the Sodor Police first Riflemen company. Harold carried the only Howitzer on Sodor.

Diesel quickly realized his error. He shoved Arthur off the nearest set of buffers, and ran off into an abandoned track in the woods. He hoped to eventually flee to the mainland and enter preservation somewhere.

Gordon had the men combing over the area. First, he ruled the mainline to be safe, and some traffic was restored on the Crovan's Gate-Barrow stretch. Checkpoints were established at every junction, and on the Vicarstown Bridge he had Howitzers mounted on flatbeds. Belle and Milosz were in charge of the Howitzers. Every train had armored Policemen, some with rifles. As the combing of Arthur's line wound down, they turned to the woods. Here was a weird network of abandoned trackage, which had to be combed by hand. Gordon had Belle, Thomas, and Bear help search crews, which he monitored from a field HQ. As they declared various points clear, Molly's branchline (Belle's former line, before she moved with Gordon to Knapford) opened again. They began to penetrate deep into the woods. They had to blast down Hiro's hideout with grenades, which Hiro shed no tears over. Gordon, however, found it to be a good place to place his War Room.

The War Room was something to behold. One large LCD panel tracked normal operations. Another showed the locations of friendly and (known) hostile combatants. Yet another showed video from various units' mounted camera headgear. Another allowed Gordon to have Video calls with subordinates in the field or the Rails. In the War Room were Gordon, the Police Commissioner, a Royal Army Captain, and several technicians. At the moment, they were Keenly tracking Harold's feed, as he combed a very promising patch of land. Promptly, Harold sighted him. He was in a patch of trees. Harold immediately radioed

"Nest Egg on feed, track 6 dash 4."

Gordon dispatched Crews to various areas, and in some places had track removed to trap the Warship. Soon, he was surrounded in 6 out of 7 exit route.

"Division 7!" Gordon yelled into the Comm, "Why in God's name are you not in position?!"

"These guns are too heavy, sir" Percy answered.

"Ditch some guns! Just blockade the bloody track!"

"Yes, sir!" the little engine puffed.

It was too late, however, and Diesel 10 gained access to a different maze. He ran over a poorly-built bridge, and barely slid onto the well-built rails.

"He's in the open!" The Commissioner bellowed. "Code Red! All units prepare to Engage!"

Engines, cars, choppers, and equipment of all kinds were brought to the area as Diesel 10 was fleeing. Gordon himself carried a Howitzer, which was brought to bear soon enough.

Belle came first, turning onto the line at high speeds, the Gun she pushed was aimed, and the Riflemen drew their weapons. The Warship tried to use his Claw to knock out the cannon, but a round to it soon changed his mind. He began to flee at top speeds. As he fled, Thomas joined Belle, and soon Bear did too. Diesel could not run forever, because soon he reached a checkpoint. A grenade to the front cab, while not derailing him, caused him to to leak oil onto the trackside. Gordon soon appeared 2km to his rear, and Harold came about as well. The Warship was trapped.

"HALT!" Gordon's voice was broadcast from Harold. "DISENGAGE YOUR ENGINE AND SURRENDER IMMEDIATELY. IF YOU DO NOT COMPLY, WE WILL OPEN FIRE."

"Go fuck yourself!" Diesel 10 screamed, and began to charge at Gordon. "DIESELS ARE SUPREEEEEEEEEEEEEEEEEEEEEEEME!"

"FIRE AT WILL!" Gordon bellowed into the comm.

Harold took a shot, piercing straight through Diesel 10's fuel tank. He was now leaking at an unsustainable pace, but continued his charge.

"FIRE AT HIS ENGINE"

Harold took aim, and shot the Warship's Engine. He was routed into a siding, and derailed, agonized by pain. Soon, he fainted.

"Who said Police Militarization is a bad thing?" Gordon asked.

The weapons were returned to the army and storage depots. Work on the Railway resumed, but Gordon still had to decide what was to be done with Diesel 10.

Diesel 10 woke up. He was on his side, in the woods, out of fuel. His horn did not work, and neither did Pinchy. He wondered as to what his fate will be.

"I shall be left on my side forever, bullets in my body."

As the days turned to weeks, and the weeks turned to months, he became increasingly validated.
