Tandro was remembered on Klaestron IV as a hero and a legend for his role in the war. In particular, he was hailed as a martyr after being betrayed by someone close to him and being killed by the rebels in 2339. His memory inspired the army and society to put down the rebellion. According to Odo, by 2369, there were statues of him all around on the planet.
That year, Tandro's son Ilon pursued an extradition order against Jadzia Dax on charges that Dax had been the traitor after he had befriended the general as Curzon Dax. It was only after the intervention of Tandro's widow, Enina, and her confession that Curzon had been in bed with her at the time of the murder, that Ilon agreed to let Jadzia go.
In reality, the general himself had plotted to betray his army to the rebel faction in the war. The rebels had returned the favor by capturing and executing Tandro. Ardelon's betrayal remained a secret between Enina and Dax. (DS9: "Dax")
