Antar System, 4 BBY

As the dark lord stepped out into the corridor of the large Star Destroyer, the sirens started sounding. A stormtrooper pair ran past to get to their posts. An officer stopped in front of the dark lord and told him that he must get to the bridge immediately, for there was an ambush sprung by the rebel alliance. A large fleet of ships were on the radar and outside the viewports. They had been surrounded. "Have we got anything from the fleet in the Corellia system?" the dark lord asked the captain of the ship, whose name still eluded him. "No sir, we have sent multiple distress signals to their sector but we have not gotten anything from them, we suspect there may have been an ambush there as well."
"What of the fleet in the Gorse system?"
"That was just defeated sir. There is a small fleet in the Abadnedo system, shall we call on them for support while we wait for the fleets on Coruscant and the fleet in the Alderaan system?"
"Yes, do that immediately."

Abadnedo System, 2 hours earlier

"Set coordinates for the Corellia system." said Grand Admiral Thrawn as he stepped onto the bridge of the Crusader Star Destroyer.

"Sir?" asked Captain Jankn.
"Do it now, our fleets in that system will be ambushed by a rebel fleet, along with the fleets in the Antar and Gorse systems, with Darth Vader in the Antar system."
"Yes sir. I will tell the commanders of the Scythe and the Crusher. Shall I tell the Emperor of this redeployment?"
"Yes, tell him that I'm redoplying my fleet to the Corellia system with a rebel ambush, and that we need him to deploy fleets to these coordinates."
"Yes sir, right away sir."

"Admiral Therson sir, multiple enemy ships coming out of hyperspace!" yelled an officer.
"How many?" asked Admiral Therson.

"2 fleets sir! We've been caught in an ambush!"
"Shit... get me Darth Vader!"
"Our communications have been jammed sir!"

"Tornado has been shot down sir!" yelled another officer, as the spray of lasers from the enemy ships started rolling towards their Star Destroyer.

Corellia System, aboard the Crusader

Grand Admiral Thrawn, sitting on his throne on the bridge of the Crusader, watched as the ship came out of hyperspace behind 2 fleets of rebel ships. "We have them in our sights, open fire," Said Thrawn calmly, "We will rip them to shreds from behind, we will save Admiral Therson from his ignorance."
"Yes sir." Replied Captain Jankn
"Tell the Intelligence to flank the enemy's right side with his squads of TIE Bombers, we will not let them escape."
"Yes sir, right away sir, should I check on the fleets from Coruscant?"
"Yes."

Corellia System, aboard the Reaper

"Admiral Therson, Grand Admiral Thrawn's fleet has dropped out of hyperspace behind the enemy fleets, and has destroyed the enemy ships jamming our communications! Enemy bombers are being shot down and we are making a comeback in this battle thanks to him! 2 more enemy ships have been shot down!"
Admiral Therson wiped the sweat from his brow. "Thrawn has certainly saved us from defeat."
A hologram of Grand Admiral Thrawn appeared in front of Therson.
"Admiral Therson, I see you have lost 3 Star Destroyers to these meek players of war. I do see they had the element of surprise, but you should have reacted with precision and without hesitation, the Emperor will not be pleased when I report your near failure." Thrawn told Therson.
"We merely did not have the numbers Grand Admiral. If we had had enough Destroyers we would have survived –"
"Quiet down now, I just saved you and the rest of your fleet, oh I did quite like the Tornado, pity you let it be shot down."
The hologram blinked off, leaving the Admiral in embarrassment.

Antar System, 30 minutes after

"Grand Admiral, our fleet has arrived in the Antar system, it seems the Emperor's reinforcements arrived before we did." Reported Captain Jankn.
"Excellent. Get me Darth Vader and the Admiral in charge of the reinforcements."
"Right away sir."

2 minutes later, thehologram screen blinked on with the faces of Grand Moff Tarkin and Darth Vader.
"How was the ambush at the Corellia system, Grand Admiral?" asked Tarkin.
"Admiral Therson nearly let the enemy destroy his fleet, if I had arrived 5minutes later, his fleet would have been destroyed. The rebels were cut apartfrom behind when my fleet had arrived."
"The fleet in the Gorse system was reported destroyed, Grand Moff Tarkin, whowas the admiral in charge of reinforcing them?" asked Vader.
"Admiral Inpetu, he was late due to an issue in the Kuat system." repliedTarkin.
"And this issue was?" asked Thrawn, who was wiping his suit off.
"A small rebel screening base, the Emperor wanted him to destroy it after itwas reported," Tarkin replied, "Grand Admiral, the Emperor wanted me to relayyou a message to redeploy the the Lothal system, the commanding officers can'tseem to deal with a small rebel cell."
"I will head there once I have my cruisers treated to."
"Excellent."
The hologram blinked off.
