[3] Another major crisis erupted in 1972 when waste disposal activities by the Italian chemical company Montedison in the Tyrrhenian Sea put the Corsican fishing industry at risk.

On 15 September 1973, another militant group, the Front Paysan Corse de Liberation (FPCL), carried out a bomb attack in Italian waters against one of the waste-disposal vessels used by Montedison at Follonica Bay, the Scarlino Secondo, using a zodiac boat.

[5] On 21 August 1975, 30 armed members of the ARC, commanded by Simeoni, occupied the farm of Henry Depeille, a wine producer of pied-noir origin who had benefited from SOMIVAC subsidies, demanding a change of policies.

Once he was briefed on the situation in Corsica, the French Ministry of Interior Affairs, Michael Poniatowski, sent in 1,200 gendarmes, eight armored personnel carriers, and eight helicopters.

[15][16] At the time of the trial on Simeoni, on 21 May 1976, a new-borne nationalist organization, the National Liberation Front of Corsica (NLFC) appeared on the scene by launching a series of bomb attacks in Ajaccio, Bastia, Sartène, Porto-Vecchio and other Corsican towns.

Former militant leader François Sargentini claimed that Aleria deepened the division between autonomists and independentists and communist activist Dominique Bucchini said that the incident "worked like a trap", diverting efforts and highlighting excesses, like xenophobia.

In the opinion of Emile Zuccarelli, deputy mayor of Bastia in 2005, the incident and its aftermath "slowed down economic development, employment and the improvement of the standard of living in Corsica".
