During the Gungan Tribal War on the planet of Naboo, the city and fortress of [Spearhead](/article/spearhead], an ancient location, was utterly destroyed. This destruction was caused by a Gungan army commanded by Boss Gallo. Sometime after humans arrived on Naboo around 4000 BBY, and millennia prior to the Imperial Era, Gallo unified the Gungan tribes. He then assembled a formidable army to assault Spearhead, which was the stronghold of the rebellious warlord Boss Rogoe and the last resistance against Gallo's unified Gungan forces. Following the city's destruction by Gallo's army, Gallo initiated the foundations of a new Gungan [capital](/article/capital], Otoh Gunga. Subsequent generations expanded Otoh Gunga as Gungans looked for refuge from both the humans and the dangerous predators of Naboo.
The initial mention of Spearhead's destruction within the new Star Wars canon occurred in Nexus of Power. This 2016 sourcebook was published by Fantasy Flight Games for the Star Wars: Force and Destiny roleplaying game. In the Star Wars Legends timeline, the Raid on Spearhead was initially referenced in Star Wars: Galactic Battlegrounds: Prima's Official Strategy Guide by Steven L. Kent. This guide was released on November 7, 2001. Later, it was featured in the LucasArts video game Star Wars: Galactic Battlegrounds, which was released on November 11 of the same year.
