The war is only mentioned by Nappa when he refers to it when talking to Vegeta about how the Saibamen he has left are the only six to survive "the crazy battle on Tritek." It is unknown when this war took place and what other factions of Frieza took place in it, but it is known that it couldn't have taken place after October of Age 761, as that is when Vegeta and Nappa plot a course for Earth.
It is noteworthy that this battle was never mentioned in the Japanese original.
