Battle of Garfagnana

The Battle of Garfagnana () was known to the Germans as Operation Winter Storm ("Unternehmen Wintergewitter") and nicknamed the "Christmas Offensive" (Italian: "Offensiva di Natale").
It was an attack of Axis forces on the western sector of the Gothic Line during World War II. It happened in December 1944 in the north Tuscan Apennines, near Massa and Lucca.
In late December 1944 the German 14th Army under General Kurt von Tippelskirch attacked the left side of the U.S. Fifth Army in the Serchio valley. He wanted to make the U.S. forces stay there.
The Allies had ordered two brigades from Indian 8th Infantry Division to be moved to help the U.S. 92nd Infantry Division. By the time they had arrived the Germans and Italians had captured Barga. U.S. soldiers had intended to retreat to Lucca. The German / Italian force stopped the attack and withdrew.
Barga was recaptured one week later by the New Year. The western Gothic Line remained in place until late March 1945.
Historical background.
Benito Mussolini and his Defense Minister, Marshal Rodolfo Graziani, wanted to create an Italian Army. They did not want this army to be under German control. They wanted some of the newly created Italian Divisions to attack the Allies in the Italian peninsula.
They planned an attack in Garfagnana for two of their new Divisions. There would be 40,000 men and airplanes. Their goal was recapturing Lucca, Pisa and Livorno in Tuscany from the Allies. But the Italians lacked arms, tanks and airplanes.
The Germans created their own attack,
With 9,000 soldiers (mostly Italians), they attacked in Garfagnana a small area of the Gothic Line. They wanted to move the Allies back .
Groups from the U.S. 92nd Infantry Division moved near Garfagnana sector in November 1944. They did not
capture Castelnuovo di Garfagnana.
