Arconovaldi Bonaccorsi (Bologna 1898 - Rome 2 July 1962), was an Italian Fascist soldier, politician and lawyer. He played a prominent role in organising the Phalangist terror on the island of Majorca during the Spanish Civil War.^[1] A prisoner of war from 1941 -1946 , after the war he resumed his legal and political activities. He was a candidate for the MSI in 1961.

Bonaccorsi is described in Georges Bernanos's A Diary of My Times. In Majorca, having arrived in the August of 1936, he was known as 'Count Rossi' , a name that derived from his red beard.

Bernanos : " Of course the new-comer was neither a general nor a count, but an Italian official belonging to the Black Shirts. One morning we saw him disembark his scarlet racing-car. First he called on the military governor appointed by General Godet. A few days later the general and his staff took up their abode in the prison of San Carlos, and Count Rossi was in charge of the Phalange. In black robes, with a huge white cross on his chest, he tore round the villages, driving his racing-car himself; other cars , crammed with men armed to the teeth, strove to keep up with him in a cloud of dust. Accompanied by the alcalde and the priest, in a strange mixed jargon of Spanish, Italian and Majorcan dialect, he announced the 'Crusade'...this gigantic brute, asserted one day at the table of a distinguished lady of Palma - whilst wiping his fingers on the tablecloth - that he required at least 'one woman per day'. But the particular mission entrusted him was marvellously suited to his gifts:the organising of Terrorism. From that time, every night, gangs of his own recruiting commenced operations in the vilages and in the very suburbs of Palma."

According to Bernanos's eye-witness report Bonaccorsi was 'well to the fore in all religious manifestations'. "He was usually supported by a chaplain picked up on the spot, in army-breeches and top-boots, a white cross on his chest and pistols stiuck in his belt.(That particular priest has since been shot by his own side.)" Bernanos recalled too in his account the particular fate of three young women of Mexican origin, whose lives one unhappy priest had begged to be spared; " 'Right' said the count. 'I'll sleep on it.' The following morning he had his men shoot them down."
