What are some (in) famous examples of psychological warfare?

During the Battle of Guadelajara during the Spanish Civil War the Garibaldi Battalion of the International Brigades, which was mainly made up from leftwing Italian volunteers, faced Mussolini’s fascist Italian Corps of Volunteer Troops. Members of the Garibaldi Battalion, knowing from Italian fascist prisoners t had captured that the supply situation for Mussolini’s troops was very bad and t were starving in their trenches, set up loudspeakers and told the fascist Italians what t were preparing for food. T also let the POWs speak to their former comrades, that t were treated and fed well. As a result many of Mussolini’s troops deserted and joined the leftwing Italians. Another issue was that Mussolini and his generals kept on bragging how tought t were. When the fighting started, t Italian fascists got soundly beaten by both the Italian leftwingers as well as Spanish Republicans, even though t were better equipped than the troops of the Spanish Republic. The Italian Corps of Volunteers became the laughing stock even within the fascist camp. The Spanish fascists sang about their Italian counterparts.
