which of the following occurred after allied forces invaded the italian mainland in september 1943?
german forces retreated from italy.
axis forces repelled the allies.
italian forces quickly surrendered.
allied forces declared victory in europe.

Explanation:

After the Allied invasion of the Italian mainland in September 1943, the Italian government, which had already been in a state of internal unrest and dissatisfaction with Mussolini's leadership, quickly surrendered. This led to the collapse of the Fascist regime in Italy. German forces did not immediately retreat from Italy; instead, they took over the defense of Italy and continued to fight the Allies. The Axis forces did not repel the Allies; the Allies were able to establish a foothold on the Italian mainland. The Allied forces did not declare victory in Europe after the invasion of Italy; the war in Europe continued for several more years.

Answer:

Italian forces quickly surrendered.
