Extract from debriefing of Colour Sergeant Sean Murphy – formerly attached to British Army SAS Regiment – given to Canadian military post-war.
[Part 2]

We had fifteen minutes warning of the approaching herd. Wing Commander Curtis (the RAF commander on-site) said that the Zombies would arrive in forty-five minutes, maybe an hour, but he was wrong. This was still early on in the first outbreak before people understood just how fast everything could turn to ****.
They came up the road towards the gate. An inbound convoy of buses had been attacked several miles away and they were the ones who gave the initial report that Fairford was about to face a strike.
The gates were at once closed and the whole base went on alert. My team and I moved into position where Curtis wanted us – not where we wanted to be, but he was an airman not a soldier – and everyone else started getting ready. The TA soldiers were sent to cover the front gate and the non-combat personnel were all moved away from there. We were up high, atop a maintenance building, with a good view of this and, more-importantly, what was happening outside the main gate.
As I said before, many civilians had been denied entry to Fairford. Short of actual violence, they had tried everything to get inside where they believed that they'd be safe. They saw the fences, the armed men and the helicopters flying other people away. The powers that be had decided to keep those hundreds of civilians outside though… which was where many of them stayed.
Those civilians had come in their own vehicles, but rather than drive away, they stayed outside the gates. The road had previously been cleared, but there were civilians in their cars parked up on either side. Those people just sat in their cars waiting to be let in. I even saw some tents – I kid you not! There were people that had stayed overnight in tents outside the main gate rather than get back into their cars and drive far away. It was insane!
The screams and shouts from those civilians, covered momentarily by the noise from a helicopter departing at high speed, announced that the 'enemy' was here.
It was by following and then attacking through the civilians denied entry to Fairford that the Zombie herd found us (in my opinion) and so quickly got here. From where I was, using my binoculars, I saw the slaughter. Words cannot describe the horrors that I witnessed. Everyone has seen pictures, video footage and even with their own eyes what can happen when people are attacked, especially by a herd. I don't need to repeat it now… and nor do I really want to.
The TA soldiers had set up machine gun positions inside the fence and around the main gate. Their trusty GPMG weapons went to work and the part-time reservist soldiers did their duty. They followed their terrible orders to shoot EVERYONE. Again and again they fired with great effect into the crowd of zombies that had come here from a great distance or just recently been infected. I kept watching: I didn't take my eyes off the sight of such mass death even though I wished to.
At once, things started to go wrong though. Many of the civilians outside, along with the enemy, moved away from the area covered by the well-placed machine guns. They went left and right away from the road. There was woodland either side and people ran into that to get away from certain death. Some fled, away from the airbase, but others followed the trace of the outer fence. They went looking for a way inside.

That couldn't be allowed though.
My team was well-armed. We had our standard-issue American M16 assault rifles, but two of my guys – Corporal's Smith and Underwood – had sniper rifles too. They both carried L115 models, which were fearsomely-accurate weapons. We were to to stop anyone from attacking the fence and were prepared to shoot at them as per our orders. One person, even five people, couldn't get across or through the fence though, no matter how determined they were.
No one, not even me (I admit) had thought that someone might crash a car into the fence about a quarter of a mile away from the main gate though. Yes, the anti-vehicle ditch stopped its forward progress – and trapped its presumably terrified, fleeing passengers inside to be soon savaged to death – but a gap had been forced in the fence.
The enemy, those Zombies, were right behind that car. They went for the people inside, and also what lay beyond. Smith and Underwood started firing at once, and I got on the radio to call for on the ground back-up, but a hole had been opened up in Fairford's outer defences.
