Hilda said, 'So this is why we've been turfed off the road. Speaking of the Germans and their speedy movements-'

In moments the tanks were on them, a line of them roaring past the parked-up bus. Mary and Hilda shrank back with the others. The tanks barely slowed down, and Mary had the impression that they would just have knocked the bus aside if it had been necessary. Close to, the tanks were huge, powerful, and the roar of their engines, the dust they kicked up, their sheer rushing mass made an overwhelming physical presence. When the tanks had passed, support vehicles followed, troop carriers and mobile artillery. There were no horse, no men on foot; this was a mechanised unit of the kind that had spearheaded the blitzkrieg that had shattered whole nations in Europe.

The column took minutes to pass. Mary saw Hilda counting silently as the vehicles passed, a bit of observation. The German soldiers whooped and clapped. The other passengers just watched with hostility, resignation or fear.

As the noise died away and the dust settled, Hilda whispered to Mary, 'I think I heard the soldiers say that was a unit of the Seventh Panzers. On their way to Guildford.'

'Guildford?'

'We have an inkling of their battle plan – plenty of spies in Berlin! And we were given pretty good briefings at the station; we needed them to do our job, you see. Evidently they're now moving forward. They're planning a break-out. It might take a couple of days to get their assets in place, and then-'

'Made a right mess of the road surface, mind.'The kidney-failure man was talking to the German soldiers. He was right; the tarmac was chewed up by the tank tracks. 'The council's going to have something to say about that, I can tell you. So is that that? Can we get back on the bus now?'

The German driver blocked his way. 'Nein. No. Not yet. Look!' He pointed down the road.

Mary saw that another column was approaching, at a much slower pace.

'Oh, for heaven's sake,' said the kidney man. 'We'll be stuck here all day.'

'Now, now, Giles,' his companion, Bill, said, 'don't annoy the nice Germans. We'll get to Tunbridge Wells for tea, you mark my words.'

That won a ripple of laughter. The Germans scowled, not understanding, suspicious.

Giles, the kidney man, didn't laugh either. 'I've had enough of this lot,' he muttered.

The second column, trundling at walking pace, was led by a couple of heavy vehicles, perhaps for recovery or clearing roadblocks. Then came more vehicles, mobile guns and troop carriers, and then troops on foot walking single file, in columns alternately to either side of the road. After that came trucks and armoured vehicles, including a couple of tanks, and then a string of carts and artillery pieces drawn by horses. As the lead vehicles passed the bus, the marching troops exchanged banter with the waiting bus crew. Some of them whistled at Hilda, and she replied with sarcastic curtseys that made them laugh.

Bill, the friend of Giles, came to stand before Hilda. 'I'll tell you what I've had enough of. I've had enough of girls like you.' A minute ago he had been elegantly joking. Now, out of nowhere, he was shouting.

Hilda was bewildered. 'Look, what do you want?'

'I saw you smiling at those Jerries. I was in the bloody BEF. We saw girls like you in France. A Jerrybag, are you, is that the story?'

Hilda flared. 'I most certainly am not.'

The bus-crew Germans came closer, uneasy. 'What is this?'

'You are what I say you are, you little whore!'

Mary stood between the man and Hilda. 'Now, you back off, buster. I don't know what your game is, but-'

The man swung his fist. Mary ducked, but she took a blow to the temple that sent her staggering. She could barely believe it had happened.

Bill went for Hilda, reaching for her throat. He was heavier than she was, and he came at her without warning. He fell forward, knocking her to the ground, his heavy overcoat flapping.

Everybody seemed to be shouting now, Hilda and Bill, the passengers. The Germans hurried forward to grab the man, trying to haul him off Hilda.

And an engine roared. Mary looked across, startled. The bus was pulling out from where it was parked on the verge. 'He said he used to drive buses. Oh, shit.' She ran forward. 'Giles! Don't do it, you'll get yourself killed!'

The Germans had hauled Bill off Hilda, but now they realised what Giles was up to, that Bill had just been distracting them. They ran at the bus, dragging their pistols from their holsters.

Giles was turning the bus around. The German troops in the column actually continued their march, evidently unable to believe what they were seeing. But when Giles gunned the bus straight at them, the marching men scattered, yelling. The first shots were fired, by some of the troopers with the presence of mind to grab their weapons. The windows of the bus shattered, but still it came on.

Mary saw it all. The bus ploughed into the lines of men like a bowling ball into a rack of pins. Some of the troops were knocked aside, some fell under the wheels. One man, grotesquely, got pinned to the bonnet like a bit of cloth, bent over backwards. He was perhaps the first to die when the bus slammed into the tank that followed the line of infantry, or perhaps it was Giles.

The bus's petrol tank exploded, a blossoming fireball. Mary was knocked onto her back.

Mary stood with Hilda. They were both smoking. Mary couldn't stop trembling.

The bus passengers stood in a loose group, guarded now by men from the column, who were, Hilda had overheard, elements of the Thirty-fourth Division of the German Ninth Army. Only Bill was kept apart. He was kneeling on the ground, his hands tied behind his back, his face puffy from the blows he had taken.

The Germans were working to fix the mess Giles had made. The column had moved into a defensive formation, the vehicles driven off the road, the heavy weapons deployed, the men taking loose cover in ditches by the side of the road. Engineers from the column were still labouring to bring the fire under control. The heavy vehicles stood by, waiting to shove the wrecks off the road.

The column's medics had set up a field station next to the road. There were seven dead, many more wounded, with broken bones, bashed heads, internal injuries. The dead lay in a short row, covered in blankets. Mary saw that some of the soldiers were unloading shovels from a supply truck; perhaps they meant to bury the dead. They seemed to need a lot of shovels, however.

The column commander, who Hilda thought was the SS equivalent of a colonel, a standartenfuhrer, was a big, cold man in a green Waffen-SS uniform. He was arguing with the bus crew, who were nervously going through some kind of list with him. Mary had no idea what they were talking about, and, numbed by all that had happened, found it hard to care.

Hilda said, 'The funny thing is, my dad would have loathed a man like Giles. He always said the upper-crust types would welcome the Nazis with open arms.'

'Then your dad would have got him wrong. And the Germans, and it cost them.'

'Yes. Any of us could have done what he did, I suppose. I mean it was suicidal, but he got rid of a good few of them, and he's held up this whole column for hours. Seen in that light, it's not a bad exchange for one life.'

'What an awful way to look at it.'

"'Take One With You. That's what Churchill has been saying.'

'Excuse me.' It was the SS colonel. He might have been fifty; he wore small round spectacles. He smiled at the passengers. 'If I could have your attention. I am Standartenfuhrer Thyrolf. I must ask you to step back now from the road. We will clear the bus and the tank, and there may be some risk to yourselves.' His English was crisp, heavily accented.
