Johan Ludvig Heiberg writes his witty, biting…

Justo José de Urquiza receives Sarmiento, whom the Federalists regard as the chief of their enemies, the embodiment of all they oppose, at his lavish country seat, San José palace.

Ricardo López Jordán prepares himself for revolution.

That revolution erupts on April 11, 1870.

As a first step, a party of fifty men under the command of Simón Luengo penetrates San José palace with the object of seizing Urquiza, but he defends himself by shooting and ends up dead.
