These were the instructions to be read over the French service of the BBC, telling the population how to react once they learned the Allies had landed.
Now aged 97 and living in Paris, he recalls with perfect clarity the excitement of the time.
“I was secretary of the Free French Propaganda Committee. There were five or six of us, and my job was to draw up the D-Day orders taking account of our discussions earlier in the day.
“We knew that the invasion was coming but of course we did not know exactly when. We had to be ready.”
Quite separate orders were broadcast to members of the Maquis. These were the famous “personal messages” read out on the BBC – often lines of French poetry that carried coded information about targets to attack.
“The main message we sent was to put France in a state of general alert. And then there were specific instructions for particular sectors of the population – like town mayors, police, factory workers and so on,” he recalls.
In fact there had been heated discussion in the propaganda committee about how far to incite the French into acts of opposition to the Germans.
The Communist party – which was extremely influential in the Resistance – wanted a immediate general insurrection on D-Day, with workers going on strike and calls to arms across the country.
Cremieux-Brilhac was part of the majority that resisted this idea.
“It would have been a very stupid mistake. The Germans would have taken massive reprisals – as indeed they did at places like Oradour-sur-Glane (a village where hundreds of civilians were massacred on June 10),” he says.
“The policy we decided on was of a gradual, phased insurrection, developing in accordance with the advance of Allied forces. In the end this is exactly what happened.”
“It is not a question of choosing to fight or not to fight; or when to fight. They are all soldiers under orders.”
“Every Frenchman who is not, or not yet, a fighter must consider himself an auxiliary to the fighters.
“However,” it goes on, “it is important that there not be – under the pretext of providing assistance – a disorganised rush to join the Resistance which would have the effect of leaving it paralysed.
Cremieux-Brilhac had particular instructions for people living inside the combat zone, ie Normandy.
They were told to “disrupt using all means transport, transmissions and communications of the Germans”.
Interestingly a line that reads “Cut telephone and telegraph lines” has been crossed out – presumably because this was regarded as the job of the Resistance.
The people of Normandy are told that “every minute lost to the Germans is a minute gained by the Allies. A car stuck on the road can delay traffic for 10 minutes – and blocking an enemy transport for 10 minutes may ensure the success of an Allied operation.”
In 1944 Cremieux-Brilhac was a 25-year-old student-turned-soldier – with already an exciting adventure behind him.
In 1940 he had been captured in France by the advancing Germans and sent to a POW camp. He escaped and made it to Russia, but there he suffered more internment (worse, he says, than under the Germans) because this was still the time of the Nazi-Soviet pact.
