A brief battle in 2154 in which a Vulcan fleet sent by Administrator V'Las tried to invade Andoria and was met by Andorian ships forewarned by Ambassador Soval and aided by Enterprise.
V'Las, head of the Vulcan High Command, claimed that the Andorians were developing weapons based on Xindi technology and assembled a fleet for a pre-emptive strike. The story is told in the Enterprise episodes Awakening and Kir'Shara.
Soval, dismissed for using a mind meld, travelled with Enterprise to warn the Andorians. Commander Shran tortured him to test the story before believing it. The Andorian fleet was in position when the Vulcans arrived, and Enterprise placed itself between the two sides.
On Vulcan, Archer, T'Pol and T'Pau reached the High Command with the Kir'Shara, the original writings of Surak. Minister Kuvak stunned V'Las and recalled the fleet. The High Command was dissolved soon after and Vulcan ended its supervision of Earth.
