On 3rd November 1968, Admiral Benigno Varela and journalist Yolivan Biglieri confronted each other with swords in Lanus and began the duel.
It all came about after Biglieri had written an article accusing Varela of being a traitor shortly after President Illia had been removed in a military coup of which Varela was a participant.
The duel lasted three rounds, a total time of about twenty minutes, but was eventually stopped by the referee (a judge) when the two men were too badly injured and bleeding profusely.
Since dueling was illegal at the time, it was denounced by several people but the cases never saw the light of day and the two men never reconciled their differences. They did however, recognise the bravery of each other, since it was agreed that they would fight to the death.
