The Fourth Division, alternatively referred to as the Fourth Fleet, represented a unit within the Rebel Alliance fleet that was active following the Battle of Hoth. This division's attempt to assemble at Rendezvous Point Delta-Three was compromised when their contact attempt with the Eighth Division alerted the Galactic Empire, leading to a blockade near a star. This blockade prevented their departure and caused the destruction of the Tyvarex due to intense enemy fire. The arrival of the Millennium Falcon at the rendezvous point created a sufficient breach in the blockade, enabling the remaining vessels of the Fourth Division to successfully flee.
The Fourth Division's composition included a minimum of three EF76 Nebulon-B escort frigates, specifically identified as the Redemption and the Tyvarex, along with at least four CR90 corvettes, a minimum of two GR-75 medium transports, one of which was the Bright Hope, and a number of X-wing, Y-wing, and A-wing starfighters, in addition to several other ships whose designs remain unidentified.
