Pol Slattery had been in command of Leopard Army for six months when they faced Salamander Army, under the command of Bonzo Madrid. Slattery was shown to be a clever commander who kept his troops moving outside of the typical practice of formations. This tactic was baffling to Bonzo and his soldiers, but it was also reckless and exposing, and resulted in Leopard losing many soldiers. However, the unexpected strategy intimidated Salamander into not fighting back. Leopard would have won if Ender Wiggin had not forced a draw by freezing 5 Leopard soldiers, so that they did not have enough men to open the gate.
Two years later, Pol Slattery was shown to be in command of Badger Army (although this may be a mistake on Card's part, as no other commander was seen to switch armies). Slattery's army battled against Ender's Dragon Army; in the battle, flashed Badger Army soldiers eventually thawed and were able to move again, but despite this advantage Badger Army lost. Slattery admitted to Ender that he was glad Dragon Army won; if he ever beat Ender, he wanted it to be fair.
- "I'm glad you won. If I ever beat you, Ender, I want to do it fair."
