Third Invasion

From Orson Scott Card Wiki

The Third Invation, later known as the War of Xenocide, was a the third and final major invasion of the Bugger Wars. Instead of the Buggers attacking Earth, it was the International Fleet ships invading the Bugger Homeworld. The outcome of the Third Invasion was Ender and the Humans attacked and destroyed the Bugger Homeworld and the buggers themself, the destruction of the Buggers eventually went down in history as the First Xenocide.
