 A little before dawn on 3 November 1867 , the Paraguayans made a surprise attack on the allied camp at Tuyutí , breaching the Argentine lines . When Porto Alegre saw the mayhem — Argentine soldiers fleeing and Paraguayans inside the Brazilian perimeter — he shouted : " Aqui morre até o último brasileiro ! " ( " In here shall die the very last Brazilian ! " ) . During the Second Battle of Tuyutí , as it was called , he fought with his saber in hand @-@ to @-@ hand combat and lost two horses one after the other . Porto Alegre and his troops , outnumbered three to one , stopped the Paraguayan advance and forced the enemy to retreat . Feeling very ill , and unable to mount a horse for a month , Porto Alegre was relieved of command on 27 January 1868 . He returned to Rio Grande do Sul and was raised from viscount to count a few months later .
