After a further trip to Africa, abridged by the necessities of his position as a pensioner of the school of Rome, he painted "Judith", then, in 1870, "Salomé", and, as a work due from the Roman school, dispatched from Tangier the large canvas, "Execution Without Hearing Under the Moorish Kings", in which the painter had played with the blood of the victim as if he were a jeweller toying with rubies. The Franco-Prussian War arose, and found Regnault foremost in the devoted ranks of the Battle of Buzenval, where he fell on 19 January 1871.
