In the islands, there will be such a horrible commotion!
All that will be heard is the noise of war.
Reprisals will be such an insult to Italians,
That they will join the allies in their fight against Hitler.

History

In this quatrain, no name of people or towns. And yet, this piece of the Nostradamus puzzle seems to fit perfectly with the Italian Campaign. Here, a whole quatrain seems to relate the same event, the decision of the italians to side with the allies in their fight against Germany. The islands are Italy, Sicily and all other surrounding italian islands. The horrible commotion is the sound of cannons, the bombings of the towns and, as if it weren't enough, the pillage and destruction by the Germans:
[P.429] The situation is confused in the whole country. [si horrible tumulte] Thousands of workers on strike swarmed the streets to demand peace; soldiers refused to open fire, thus contravening to martial law that forbids strikes and manifestations. A few fanatics barricaded themselves inside the headquarters of the fascist party, and stories of lynching are spread throughout the country. Since the removal of the duce five days ago, events follow one another : democrats are in favor of an alliance with the allies to fight the german army... Badoglio, Mussolini's successor, does not have much room to manoeuvre. General Eisenhower offered him to return the prisoners if Italy stops cooperating with the Germans. The new Prime Minister wants his country out of the war, but it remains to be seen how he will manage to throw the war out of the country...

Signature of the armistice

Now occupying Italy, the Germans behave in such a cruel manner that they alienate the respect and support of the Italian people:
[P.446] ...THE ITALIANS FACE TO FACE WITH THEIR FORMER ALLIES.
A tragedy for the italian army. Afer signing the armistice, members of the government flee the capital along with Badoglio [now in charge] and the royal family, leaving no directives to the military. Refusing to surrender, the soldiers of general Gandin resist the germans. And today, having exhausted their munitions, they surrendered. By way of reprisal, the Germans decided to shoot their italian prisoners; five thousands soldiers and officers were slaughtered, more than fifteen hundred died while trying to resist. [tant grande sera des prédateurs l'insulte] Finally, three thousand have been engulfed with the vessel that was carrying them to Germany...
September 3, Badoglio signs the armistice with the allies. October 13, he declares war to Germany. It was a terrible blow to the Germans. It made a breach in the unshakeable faith the nazis had placed in Hitler and his generals.:
[P.440] ...Casibile, september 3, 1943.
Having maintened silence about the negociations, general Castellano signs the agreement by means of which Italy withdraws from war. American general Walter Bedell Smith, Eisenhower's chief-of-staff represents the allies. [la grande ligue] This armistice will be announced at the appropriate time in order to avoid a violent reaction on the part of the Germans that would translate into the complete disarming of the italian army and the occupation of Italy by the Germans.
