I want to know the answer to the following question:
In which city did many Italians attempt to proffer their services to the Prussian embassy?
All the background I'm provided with is that "When the war had begun, European public opinion heavily favored the Germans; many Italians attempted to sign up as volunteers at the Prussian embassy in Florence and a Prussian diplomat visited Giuseppe Garibaldi in Caprera.". Is that enough to answer the question?
Answer: yes
