Note: As you'll see, this part is mainly about the events that happened to the Allies in these days, and there won't be any Soviets in it. The Soviet reaction, together with the German and Italian reaction, will all be covered in the next part. There will also be more pictures after this part. I hope this part is still interesting enough without them...
Chapter 1: The Road to War
Part 2: The Allied Reaction
Bordeaux, 12.00, November 16th
Maurice Gamelin, Pierre Laval, Francois Darlan, Victor Denain, Stanley Baldwin, Anthony Eden, Sir A. Montgomery-Massingberd, Sir Ernle Chatfield and Sir Owen Boyd all sat around the large table inside Gamelin's HQ. The atmosphere was tense. The main figures of the British and French governments had been summoned together here in light of the very recent events in Spain.
Laval: "At 3.00 this morning, Nationalist Spain declared war on the newly independent state of Catalunya. Already we have received reports of Fascist crimes against humanity. The government of Catalunya has also sent us messages for help. Also, Fascist troops have provoked skirmishes near the town of Hendaye on the Spanish border. The hostile actions of the Fascists are concerning our population and our generals. We propose that we should act quick and bring back peace to Spain and the rest of Europe. We shall, however, not act without full support from Great Britain and the Commonwealth."
The British representatives consulted each other on the matter. After 5 minutes Baldwin spoke:
"Britain shall support every action by the French in this matter."
Laval: "Very well then. We shall sent an ultimatum demanding the retreat of Fascist forces out of Catalunya and away from the French borders. They have until 17.00 tomorrow to comply. Gamelin, send out the order of mobilisation for the French army. Darlan, sail out the navy and block the shipment of all German and Italian equipment to the Fascists."
Baldwin: "Won't that be too risky? I don't think the Germans and Italians will like it when we block their shipments."
Laval: "We'll have to take that risk."
Pierre Laval, French Head of Government
Bilbao, 16.00, November 16th
Bautista: "Generallissimo, we have received an ultimatum from France demanding that we immediately withdraw our forces from Catalunya and away from the French border near Hendaye. We have until 17.00 tomorrow to comply. If we refuse, France, Great Britain and the Commonwealth will react with military force and will block all supply shipments from Germany and Italy.
Franco: "They're bluffing. They know the Germans and Italians will be infuriated if their supply shipments would be blocked. They will not risk a two-front war at the time. Ignore the ultimatum and proceed as planned."
Bautista: "Yes Generallissimo!"
Paris, 17.00 November 17th
Laval: "Sherald! Have we still not received any answer from the Fascists?
Sherald: "No monsieur. Nothing."
Laval: "Gamelin, Darlan, you know what to do. Sherald, send the declaration of war to the Fascists and inform the British. I will be informing the French people."
Within one hour, Laval could be heard on every radio in France.
"Yesterday, an ultimatum has been sent to the Nationalist Spanish Government, demanding the immediate withdrawal of all Nationalist Spanish forces from the newly independent state of Catalunya, and away from the French border near Hendaye. If we would receive no answer before 17.00 today, a state of war would exist between France and Nationalist Spain and, consequently, also between Great Britain and Nationalist Spain.
We have still not received an answer, meaning that we are now at war with Nationalist Spain.
You may be taking part in the fighting Services or as a volunteer in one of the branches of civil defence. If so you will report for duty in accordance with the instructions you have received.
I sincerely hope that this war will be ended swiftly, and that peace can be brought back to Spain and the rest of Europe, and that there will be no interventions from foreign countries.
As everyone knows, good always prevails."
