I found out about this battle in the Most one-sided war thread.
OTL, the battle was a complete failure for the Triple Alliance, as they lost 10,000 killed and wounded out of a force of 20,000 against the Paraguayans losing only 23 killed and 79 wounded. The only thing that prevented total disaster for the Triple Alliance was Paraguayan President Francisco Solano Lopez's refusal to order a counter-attack against the defeated and exhausted Brazilian-Argentine army.
So let us presume that Lopez orders General Jose Diaz, the Paraguayan commander in the battle, to counter-attack. With the remaining Triple Alliance forces exhausted and many already starting to flee on their own, the result would probably be an utter rout. What then? Does the Triple Alliance decide to start negotiations, or is the war merely prolonged?
