The second validation program was soon undertaken.

As Dwig estimated, the plan went very smoothly, and German intelligence officers managed to exchange a few bundles of pounds sterling for $90,000 in Swiss banks, knowing that the dollars could be exchanged for gold directly from the central bank (one dollar was worth 0.888671 grams of gold).

So this can almost be regarded as a direct exchange for wealth.

The Security Bureau let out another cheer when it received this information...... The nature of this successful exchange was fundamentally different from the previous one, because the intelligence officers obviously observed the different faces of the staff of the Swiss bank, and they even avoided it for a while, apparently to hold a meeting to discuss how to solve the exchange of this "suspected counterfeit banknote".

But in the end, they had no choice but to accept the pounds...... They didn't have any evidence to prove the counterfeit bills, so they just knocked out their teeth and swallowed them in their stomachs.

For Qin Chuan and others, this actually confirms one point from the other side: the British side has no effective way to distinguish the authenticity of these pounds.

"But we can't be sure yet!" Colonel Koch added in his excitement: "Because this may be an implicit compromise on the part of Switzerland under some kind of pressure, such as political or military considerations!" ”

Although Colonel Koch did not explain further, Qin Chuan knew what he meant.

At this time, Switzerland was one of the few neutral countries that was not occupied or controlled by Germany.

But there is a saying that "there are no eggs under the nest", and the reason why Germany did not occupy Switzerland was not because of the posture of Switzerland...... Sending hundreds of thousands of troops to defend the border is not because the Swiss army is so combative, and still less because Switzerland affirms its neutrality in the war.

In fact, at this time, Germany only needed to send a random corps to occupy the entire territory of Switzerland in a few days, and even Hitler estimated that Switzerland would not dare to resist...... The reason is that the Swiss army is nothing compared to Germany, and most of the surrounding countries and regions are under German control, and Germany's war against Switzerland can almost be said to be a "war of encirclement".

This was not done because Hitler considered that it might be more advantageous not to occupy Switzerland than to occupy it.

What did Germany gain by occupying Switzerland?

Switzerland did not cooperate, so Germany had to send extra troops to garrison it, and then, like other protectorates, had to deal with underground guerrillas.

On the other hand, Germany had many advantages not to occupy Switzerland.

For example, Switzerland's full cooperation...... For example, the opening of the Gotthard and Sinjinlong tunnels from Germany to Italy, and the production of arms for Germany.

Of course, anyone with a discerning eye can see that this is actually the Swiss strategy.

As the saying goes, "there are only interests between countries", Switzerland did this to make Hitler understand one point: as long as you don't attack Switzerland, you can negotiate anything, arms, supplies, transportation, what you can provide you with will be provided to the best of its ability, once you attack Switzerland, it may not be so.

Even Switzerland took a hard line stance: the Germans had to pass through the two tunnels mentioned above in order to get supplies and troops to Italy. Switzerland had already planted a large amount of explosives in the tunnels, and if the Germans invaded Switzerland, the Swiss would immediately blow it up, which would cut off the only link between Germany and Italy, and the consequences would be unimaginable. And this was something that Hitler did not want to see.

Thus, after balancing these interests, Hitler saw no need for occupation.

Similarly, Sweden opened up its own transportation and even directly helped Germany transport troops and supplies.

This is a reluctant choice made by a small country caught between the struggles of the great powers, and it is undoubtedly the right thing to do from the perspective of national interests. But the so-called "neutral countries" are just a fig leaf.

In this case, it is also possible that Swiss banks did not accept the pounds because of the pound itself, but because of pressure from the German side.

However, it was not difficult to verify this, as a few days later counterfeit notes worth 300,000 pounds were also shipped to London.

On this day, everyone waited with bated breath for news from London.

It seemed like a bit of a surprise, for the first exchange should have been completed half an hour earlier, and the telegram of the exchange results should have been received by this time, but the correspondent had no news.

"Is the exchanger British?" Qin Chuan asked.

"Yes!" Colonel Koch replied: "A bankrupt merchant who was bribed by the intelligence officers, we paid him two thousand pounds!" ”

"Are counterfeit banknotes separated by pounds of different denominations?" Qin Chuan asked again.

"Of course!" Colonel Koch replied.

This was because of Dwig's reminder that in order to make the exchange more concealed, intelligence officers mixed counterfeit banknotes with genuine banknotes, and there were also banknotes of different denominations.

But in fact, Qin Chuan also knew that this would not have any effect.

The reason was that it was a time of war, and Britain was under a total blockade by Germany, and rationing was also in place, so it was impossible for ordinary people to carry or even few people to have so many pounds sterling, and to exchange them would certainly arouse the suspicion of bank staff.

However, in a way, this is exactly what Qin Chuan wants, and Qin Chuan wants to see how the British side will deal with this batch of counterfeit banknotes.

After waiting for about twenty minutes, the correspondent finally received a message, and the translator excitedly reported after translating: "The exchange has been successful!" ”

Everyone couldn't help but breathe a sigh of relief and congratulate each other, although this was expected, but they still secretly pinched a sweat.

It is clear that the British have chosen to settle the matter, and they do not want the impact of this incident to expand.

But this approach obviously does not solve the problem, because it has already allowed Colonel Koch and Qin Chuan to confirm that this version of the counterfeit banknote can enter mass production.

The news soon reached British Prime Minister Churchill.

Churchill looked at the telegram with a dead face, and then he asked two questions.

The first question is: "How large?" ”

"It's not a big scale!" The staff officer replied: "A total of 500,000 pounds for the Swiss bank, 300,000 pounds for the Bank of England!" ”

After thinking about it, Churchill, who was holding the telegram, asked again: "All in 10 pounds?" ”

"Yes!" The staff officer nodded.

Churchill smoked his cigar violently, his brow furrowed in the smoke.

He knew that this was a dangerous signal from the Germans, or rather, a temptation by the Germans, and that it was time for the widespread flow of counterfeit money into Britain.

After a long silence, Churchill asked: "Is it possible to recover the 10 pounds of sterling?" ”

This may be an approach, but it is only a stopgap measure.
