Rendezvous Point Lambda-Four was a Rebel Alliance rendezvous point, situated on the edge of an impact crater on the Outer Rim Territories planet Ab Dalis. The rendezvous point contained a resupply depot and mechanical facilities for repairs. After the Alliance Fleet split following the Battle of Hoth to avoid the Galactic Empire, the Eleventh Division, whose forces included Chancellor Mon Mothma, situated themselves at Rendezvous Point Lambda-Four. The rebels were attacked by Admiral Kalaxo of the Star Destroyer Ultima II, who destroyed the forward ground defense base. The Ultima II was subsequently destroyed when the Alliance's Starlight Squadron, who had been searching for surviving rebel divisions, activated a dormant volcano that the starship had parked above.
