The preparations for the evacuation were in full swing when Lieutenant Connix saw the First Order fleet drop out of hyperspace.
Corran looked at the sky and knew immediately that it was too late to bring everything aboard the transports and the few capitol ships the Resistance possesses. It was only enough time to bring the ships in orbit with the equipment and fuel already on board. He headed to his X-wing that would bring him to General Organa's flagship the Admiral Raddus. The MC85 Star Cruiser formerly named Dawn of Tranquility and now renamed after the famous admiral who was killed in action over Scarif decades ago.

When he arrived on board he saw Poe Dameron jump out of his X-wing and run to the bridge followed by his faithful astromech BB-8. The young Jedi wondered what his commander was up to. Minutes later he should learn about Poe's rakish plan.
"You really want to take on the Dreadnought alone, Poe?" He asked Dameron after the ace pilot explained his plan.
"Of course," Poe answered him. "It's risky but a skilled pilot can accomplish it, Corran. We must buy time and take most of the Dreadnought's turbo lasers out before Cobalt Squad arrives."
"Then let me do it, Poe."
Dameron shook his head. "No, Corran, your mother would kill me if anything would happen to you."
"But…"
Poe broke in on him: "But me no buts, Corran."
Then he turned to prepare for combat.
Corran looked after him wondering if he would see Poe again or if the pilot would die trying to buy time for the fleeing Resistance fleet.

The Jedi went over to one of the viewports.
A few minutes later he saw Poe's X-wing head for the First Order fleet. A few clicks away he stopped and hovered in space. Corran frowned wondering what Poe might be up to. It seemed an eternity until the X-wing was set in motion again. With an extra boost of the newly installed experimental thrust accelerator pod, designed to give Black One even greater combat speed, Poe's fighter headed for the Dreadnought and begun his strafing run on the turbo lasers. Corran held his breath when he saw TIEs launch and engage the lonely X-wing. Nevertheless Poe took out one turbo laser after the other. Finally there was only one left, but nothing happened.
Corran cursed inwardly seeing this and having no idea what happened. He felt Poe's emotions in the Force and it didn't help him to keep calm. The Jedi's nerves were on edge when the minutes ticked away before Poe was finally able to take the very last turbo laser cannon out.

Not too early then the MG-100 StarFortress bombers just arrived. Accompanied by fighters to protect them they made their attack run on the First Order fleet and the Dreadnought as their main target. But then everything went terribly wrong. The bombers were immediately under attack. They were too close together and when one of them was hit, the payload exploded and hit the adjacent bombers. It was an unstoppable chain reaction. The Jedi felt anxiety and despair from the attacking Resistance Forces members. It didn't take long and there was only one bomber left. Corran slammed his fist against the viewport's transparisteel. "Sithspawn!"
The very last StarFortress hovered over the Dreadnought and nothing happened.

Corran felt the emotions of the only survivor on board. There was first despair but then despair changed to resolve and determination. Finally the bomb bay opened and the proton bombs hit their target. Corran sighed when he saw that it wasn't only the Dreadnought going down in the inferno. The battle was over for now and the Resistance has paid a high death toll.
The young Jedi turned away from the viewport and headed to the hangar bay just the moment Poe Dameron landed his X-wing.
