During the time of the Galactic Civil War, the Bothan Spynet executed an intelligence operation for the Alliance to Restore the Republic. This mission resulted in extensive loss of life, with numerous Bothans among the casualties; however, the spynet discovered that the Galactic Empire was building a second Death Star located at the moon Endor within the Moddell sector. Furthermore, the Bothans successfully obtained footage from Endor showing the Death Star II being constructed, which was presented to Alliance High Command and the Alliance's leading admirals and generals at a gathering on Zastiga less than a week following the operation.
