Cal checked his watch as they pulled out of the square heading back to the bridge, waving away the excessively pungent smoke of the cigar-thick French cigarette Peter had just lit up.

‘I am going to presume they don’t know where the cargo is; for instance, like you, they have no idea it’s on a barge. If they did, why tail us, given there is only one way out to sea?’

‘And in order to tell their mates they have located them they need a telephone, which means they must come back here, since we doubt there’s one closer that they know about.’

‘Their chums can’t move to intercept until they know where to go. So maybe we should lead them to that farmhouse and set a trap.’

‘Which neither you nor I would walk into, Cal.’

‘But then we would not have been spotted if we wanted to tail anyone, would we?’

‘Are they stupid or just cocky?’

‘Bit of both and certainly the latter, I’d say. I don’t recall ever meeting a French über-patriot but they are of a type, no different to their German counterparts, full of themselves and sure that God, ideology and history are on their side.’

As if to prove what he had just said the Hispano-Suiza appeared once more in the rear-view mirror, a fact that Cal passed on. The situation was the same, driving without haste, except this time as they crossed to the southern side of the bridge he stopped and waited, seemingly indecisive, looking left and right, his tail pulling up likewise before his wheels hit the crossing.

‘Seven minutes,’ Cal added, looking at his watch again. ‘Say ten minutes to get to that phone, make the call and drive back to the bridge. He’s bound to drive like a bat out of hell.’

Peter reached into his pocket and pulled out a penknife, looking very smug indeed as he opened the blade. ‘Except, when he gets there he will find the instrument does not work.’

‘You cut the connection?’

‘No point in just being a passenger, old boy, and I reckoned you had paid the old biddy who owns the shop more than enough to cover the repair.’

Cal nodded and moved off, driving straight into the jumble of barns to pull up beside the two lorries, slightly annoyed as they got out that two of the men who had agreed to aid him came out of the largest barn to greet them and thus made their presence known.

It would have been pointless to chastise them even if he had the power, so he just smiled and raised his hand in welcome, while telling them to get ready to move; he planned to be well away from here when the roadster came back.

The roar of that car’s twin exhausts alerted them to the fact that any previous calculations, such as sending the lorries in different directions, were useless. The Hispano-Suiza swept over the bridge, turned right and, with the driver’s foot right to the floor, shot off down the road to La Rochelle.

‘One assumes,’ Peter said, with his usual studied calm, ‘that the chums are already on their way and our Johnnies have gone to meet them and chivvy them along. We have been humbugged, old boy.’

Cal’s response was not calm, it was a loud and foul expletive followed by a stream of rapid French as he informed those he had brought with him – another quartet had emerged to make six in all – about the danger they were in, that followed by a set of rapid instructions.

The most important were to despatch the two Basques to tell the owner of the barge, who had stayed aboard to guard it, to get it moving towards the port and an insistence all three ignore anything else that happened around them.

He was still talking as he dashed to the nearest lorry to open the passenger door, reaching under the seats to pull out a roll of sacking, which, when rolled open on the ground, revealed the matt black metal and wooden stock of one of his Czech ZB26 light machine guns, complete with spare barrel and the front bipod, which he began to assemble and load, before dragging out and opening a canvas backpack to reveal several box magazines.

‘Peter,’ Cal said, removing and handing over his jacket, ‘take my car back over the bridge. Get it out of sight, then cross back over and keep an eye on the road from La Rochelle. Oh, and you might need that spare clip for the Mauser.’

His old army comrade was looking at the machine gun and he was clearly worried. ‘You can’t start a war, Cal.’

‘I’ll try not to, Peter, but these sods have to be stopped and I don’t think blowing kisses at them will do the trick. Now please do as I ask and quickly, we don’t know how long we have and I need to think of a way to throw them off their game.’

With no idea of numbers or the level of the arms they might be carrying, Cal knew one very pertinent fact: with lorries likely to be against cars he could not outrun them, which would mean whatever he did, flight would only bring on a contest and in the open country, where he would be at an even greater disadvantage than he was at present.

So he had to think of a way to stop them getting into these farm buildings, a place he could easily be driven out of unless he was prepared to use the machine gun, and that might bring about, depending on how aggressive those heading this way were and regardless of his own disinclination, the need to kill.

Given no alternative that is what he would have to do, but quite apart from the bloodshed there was a second consideration in terms of the discreet smuggling out of a barge-load of weapons. It would hardly help to have the whole region, and probably the town and port as well, crawling with gendarmes after a gun battle and several fatalities.

He was also responsible for those Frenchmen, dock workers who had come along to help their fellow anti-fascists in Spain. They might be committed enough to run the risk of arrest but they were not armed, only along to provide the muscle he needed to load the weapons on to the ship, and now a quartet were looking at him waiting to be told what to do and right at that moment he was struggling for a solution.

It was the recollection of the lorry he had passed on the way here as well as how difficult the squeeze had been that gave him the idea, but just blocking the route would not be enough and he cast around for an added factor, looking at all the old bits of farm equipment until his eyes lit on a large drum surmounted by a lever pump.

The commands might have been rapid but the obedience was frustratingly slow from men who were willing helpers but not fighters. Cal was obliged to not only repeat his wishes but to cajole and push them into compliance before he could get the lorry started and back it up so the drum could be loaded on the back.

While they were doing that he went to find something easily combustible once soaked with petrol, alighting on a bale of straw, and then he had to get them to understand his aim, which took a quantity of arm waving until the nods looked convincing and he could get back behind the wheel and start the engine.

With the loaded light machine gun and spare mags on the seat beside him he eased the lorry out over the rough ground, which risked that drum being tipped off over the dropped wooden tailgate, obvious by the shouting telling him to slow down as it bucked and swayed over the deep dried-out ruts that criss-crossed the yard.

That ceased as they made the smooth surface of the pavé road, where he could also jam down on the accelerator, not that it produced much in the way of pace in a vehicle old and fatally underpowered.

It was just as well he had no need to go far; Cal wanted those thugs who were on their way to keep looking at what lay behind the lorry, to be able to easily see what he intended they should: the second one making a getaway.

On a long straight road and in his slightly elevated position he saw the first of a long convoy of some ten cars coming in good time, the J12 in front, not racing but at a steady pace that was somehow more threatening than all-out speed.
