==The battle==

On July 17, 2552, [[Ensign]] [[William Lovell]] logged a large gravitational anomaly inside [[Slipstream space]]. Deciding that it could not be any form of [[Covenant starship]] based on its immense size, Lovell passed it off as an asteroid, sent his hourly report, and thought nothing more of it.<ref>'''Halo: The Fall of Reach''', ''pages 137-138''</ref>

Despite the hopeless tactical situation, Commander Keyes resolved to attack. The ''Iroquois'' set a collision course for the destroyer at emergency acceleration while launching a nuclear warhead in what seemed to be the wrong direction. The two escorting frigates proceeded to launch a salvo of [[plasma]], but the ''Iroquois'' managed to evade by utilizing the emergency thruster. Having missed their target, the plasma came about and continued to track and home in on the [[United Nations Space Command|UNSC]] warship.<ref>'''Halo: The Fall of Reach''', ''page 174''</ref>

===Operation: OCEAN BREAKER===

With a group of surviving civilians evacuated, the SPARTANs returned to H.Q. and detonated a [[HAVOK Tactical Nuclear Weapon|HAVOK nuclear warhead]], destroying Côte d'Azur and removing the Covenant presence on the planet.<ref>'''Halo: The Fall of Reach''', ''page 230''</ref> Other cities on the planet would be destroyed, such as [[Caracas]], [[Huiren]], [[Silma]] and [[Enfield]], either due to similar Covenant invasion or to preemptive destruction by the UNSC to deny the Covenant the objects they sought.<ref name=BRAVADO>[[Halo Waypoint]] - [http://www.halo.xbox.com/Content/assets/en-us/ONI/239409409548923768/DDR-A340021-2300-07-18-52.pdf Data Drop Two]</ref>

===Second space battle===

With the ground battle continuing, more UNSC ships arrived in orbit over Sigma Octanus IV. At 0625 hours, a [[Second Fleet of Solemn Accord|fleet]] of Covenant vessels were detected on the edge of the system. The 48 available UNSC warships, including the ''Iroquois ''and Stanforth's flagship, the ''Marathon''-class cruiser ''Leviathan'', formed a tight "checkerboard" formation that allowed for them to fire all their [[Magnetic Accelerator Cannon|MAC]] guns simultaneously at the Covenant fleet with a single massive volley. However, this restricted the mobility of the UNSC fleet, and left them unable to evade the extremely accurate Covenant plasma torpedoes. When the battle commenced, the Covenant fleet took a severe beating from the UNSC's opening MAC salvo, but promptly returned fire with a salvo of plasma torpedoes. The repair station ''[[UNSC Cradle|Cradle]]'' moved in front of the UNSC formation, acting as a sacrificial shield, and absorbed the Covenant fleet's first salvo, at the cost of the station and its entire crew. This allowed the UNSC ships to dedicate all the power from their reactors to recharging their MAC guns, and the UNSC ships were thus quickly able to fire a second salvo after the destroyed ''Cradle'' drifted away.<ref>'''Halo: The Fall of Reach''', ''page 222''</ref>

==Aftermath==

{{Main|Operation: BRAVADO}}

A spy probe attached to the destroyer ''Iroquois'' led the Covenant to [[Reach]], which they attacked a few days later.<ref>'''Halo: The Fall of Reach''', ''page 247''</ref> It later transpired that the Covenant had learned the location of one of the Halos from the transmission, which they planned to activate to begin the [[Covenant religion|Great Journey]].{{citation needed}}

*'''0000 Hours:''' [[William Lovell|Ensign William Lovell]], aboard the [[United Nations Space Command|UNSC]] [[Remote scanning outpost|Remote Scanning Outpost]] ''[[Archimedes]]'', reports to Sigma Octanus IV concerning a large silhouette in [[Slipstream space|Slipspace]] heading for the system. It is suspected to be a group of Covenant ships but it could also be an asteroid.

*'''0300 Hours:''' The {{UNSCShip|Iroquois}} arrives in system on patrol. The vessel's Commanding Officer, [[Jacob Keyes|Commander Jacob Keyes]], receives the sensor information and realizes it is a Covenant threat. He contacts [[UNSC Fleet Command|FLEETCOM]] and informs them of the situation.

*'''0330 Hours:''' The ''Iroquois'' destroys all Covenant vessels save for the carrier using a maneuver later known as the [[Keyes Loop]]. The carrier launches landing craft toward Sigma Octanus IV, then retreats into slipspace.

*'''0345 Hours:''' Covenant ground forces invade the city of [[Côte d'Azur]] on the planet.
