Meanwhile In Orbit above San Angeles:
The UNSC Naval fleet was putting up a fight as long as they could. Vice-Admiral Harrison was on board the Vigorous Inferno, leading Battle-group Zeta against a Covenant group. Harrison had his Valiant-class super-heavy cruiser, defended by four destroyers and four frigates, going up against a CCS-class battle-group. Harrison had them outnumbered three to one, but for all Harrison knew, the Covenant could win this fight.
Harrison: Weapons station, prepare to fire the MAC! Arm archer missile pods twenty to fifty! Fire on my mark.
Harrison spun in his chair and turned to one of his comm officers.
Harrison: Inform the rest of the battle group to fire on my mark!
Comm Officer: Fire what, Admiral?
Harrison: They will know!
Harrison spun again, and faced the view screen of the approaching Covenant cruisers.
Harrison: Target the cruiser on the left, force them to move closer!
Weapons Officer: Weapons locked, Admiral, ready to fire!
Harrison waited, he watched the view screen of the three CCS-cruisers approaching his group. He knew that with the death of the UNSC Varrox, he was the commanding officer of the entire UNSC Fleet. He only hoped his plan would survive the next few moments to accomplish their mission.
The cruisers were approaching fast.
Weapons Officer: Admiral, they have a lock!
The weapons officer instantaneously hit a button and sent the thirty pods of archer missiles at the left most cruiser. The cruiser swayed to it's right, trying to dodge the incoming missiles and heading closer to the middle cruiser. The middle cruiser had managed to fire off it's plasma cannons before having to break off, destroying one destroyer in the process. The other ships in his battle-group fired their archer missiles and the other two, forcing the right most cruiser towards it's left. The three ships were headed for a collision course on each other.
Harrison: Fire the MAC rounds! Inform all ships!
Officer: Aye, aye!
All eight ships simultaneously fired their MAC rounds at the three ships, penetrating the shields, and eventually the hulls. Harrison's slug had managed to break through the first ship and end up hitting the shields of a second, as the cruisers were basically in a firing line.
The Covenant ships could not sustain themselves and within moments lost power and eventually began to blow up, level by level.
Officer: Three CCS-cruisers offline and being ripped apart as we speak.
Harrison nodded. He looked at another view screen, the UNSC fleet was putting up a good fight, they were holding and reports from the ground were saying the same.
Radar Officer: Admiral! Multiple slipspace ruptures at the far end of the battle! Putting it up on view screen four!
Harrison turned his head to the fourth view screen. Harrison watched as a second Covenant armada came through, the ships had no cohesion, and the flagship was red and gold. Harrison took a deep breath. The UNSC was severely outnumbered, outgunned, and the morale was dropping fast. They would not survive the next few hours if they continued to fight the way they were.
Harrison: This battle is not one we can win conventionally.
Harrison turned to his communications officer.
Harrison: Fleet-wide broadcast, now!
The officer nodded and pressed a few buttons, Harrison was speaking to every ship in the fleet.
Harrison: UNSC Navy, this is Vice-Admiral Fredward Harrison, acting commander of the battle-group. As you may have just seen, a second Covenant armada has broken through and is currently en route to our position. We will not survive the battle if we continue to fight conventionally.
Harrison: I want every ship to arm at least one of their Shiva-class nuclear warheads and send it at the new Covenant armada. The EMP will cause their systems to malfunction and give us enough time to regroup!
An officer from a frigate broke onto the line.
Officer: Admiral, what of the ships currently engaged!
Harrison: Once we detonate the nukes we will have enough time to regroup and help the rest of the fleet. At the moment, you all have your orders! Regroup on me once the nukes are away! Harrison out!
Harrison nodded at the communications officer and the comm line closed. Harrison turned to his weapons station officers and looked at them.
Harrison: Arm three of our nukes and remotely detonate them on my mark.
The officers nodded and went to work, the new Covenant armada was fast approaching, but Harrison had faith that the fleet would hold until his plan was complete.
Officer: Admiral! Longsword pilots are requesting new orders!
Harrison: Recall all pilots, we are going on lock down until we are clear!
Officer: Aye, aye, sir!
Harrison sat in his chair and took a deep breath. He looked around the bridge, he had a view of every ship currently engaged in battle. Many ships were retreating as they had launched their shivas and were en route to regroup with Harrison. However, a few ships were still engaged in fire with CCS-battlegroups. Harrison hoped he would have enough men to save the others.
Weapons Officer: Admiral! All nukes away, fifteen seconds to target! All ships respond that they have sent nukes. The Covenant ships however, have halted...they are sitting just outside the optimal firing range.
Harrison: Interesting...they may know of our plan. If any get to close, detonate the nuclear weapons.
Meanwhile on board the Perilus Avenger.
Dangerus was sitting in the command chair, watching the Covenant fleet engage the UNSC. He was weary of the events that had taken place, an entire armada destroyed and his only alternative to join the ships currently in battle. He had noticed that the UNSC was taking a beating, but currently holding the line. Dangerus then watched as the ships began to regroup with another. As his ship started to malfunction. Dangerus growled.
Brute: Unknown, something is causing our systems to fail.
Dangerus growled, he saw this tactic before.
Dangerus; All ships halt! We are approaching an area littered with the human's nuclear weapons!
The brutes on the ship powered down the engines and informed the other ships in the armada to do the same. All the ships halted their advance, only a few hundred meters from the optimal firing range.
Brute: Chieftain, our Covenant brothers are dying, we must move!
Dangerus: And risk the demise of my entire fleet!?
Dangerus: Hold here! I must think of an alternative...
Meanwhile on the surface of San Angeles:
Omega Legion were currently in the middle of a firefight outside of a evacuation port. They were holding the line against a battalion of Covenant forces. Four ODST squads were trying to evac all the civilians before they were overrun. Carmicle, Limos, Colby, and Troy were all behind cover near the evac center.
Carmicle: Limos, up on your left!
Limos stood from cover and fired his SMG at the elite running up on the left side. The SMG rounds deteriorated the elites' shields and an extra kick from Troy's assault rifle killed the elite. The Covenant was making no advance.
Suicide Squad was on the other side of the planet, in the middle of the night. They were ordered to drop in and destroy a Covenant landing zone. The zone was being used to transport weapons, supplies and troops to the surface. The Suicide Squad had one shot, get in, blow the place to hell, and then evac the area. Their survival was slim to none, then again, it was the Suicide Squad. The squad was currently moving through a thicket of trees, hoping to sneak into the area before having to go loud. Radio silence was a must for this operation, night-vision was a crucial aspect to the success of the mission, as well as the act of surprise.
