Star Wars: What happened to Captain Rex after order 66

The Mission

Chapter 4: The trap
The soldiers got in to the planet, "undetected as they thought. Do they started getting ready for a long journey, to an old command base in the North. This group was made of the 11 soldiers plus an unexpected companion: Mark Solo, Captain Black, Commander Red, Greenex, Bravo 5, Sargeant Neco, Admiral Plain, Craxy Wex, Wesquer, Neacbar, Commander White. Who was Mark Solo you wander. Well, he was Han Solo's brother. When they arrive to the base on the North of Kashyk they found something unexpected. They saw Empire Clonetroopers and wookies working for the Empire. They had to find a way to get in that base and destroy the base. Luckily Greenex had worked in that base and know an air vent they could use to get in. Once in the air vent they got until the power room. This, seemed too easy for them. They got in the power room, planted explosives and set the timer. The only way out now was the back door but before take some guns. They walked for the door of the power room to leave but to their surprise, it was locked, for a minute. Then it opened and troopers came in with wookies to trap them. They only had two choices, be captured or fight. They went with the fighting. Using boxes as cover they got rid of about 20 troopers and 6 wookies but more came. If they threw a bomb it would blow the whole room. Faster acctually cause it still was going to blow cause of the timed bombs. Neacbar gets shot down while trying to get to Mark. Seargean Neco with Craxy go to get him. Neco gets grabbed by the chocked by a wookie, and Craxy starts shooting. Craxy did a sacrifice. He told the others to get out of there but first get the guns. He gets two rifles and shoots everything in his path. He then gives Mark his lightknive. Is kind of a mini lightsaber. Mark cuts the wall to another room. From there they escape but White dies in the attempt. Craxy runs out of ammo an gets shot. Mark knew he had to think quick so he told his men to get supply bags which contained decent ammounts of weapons, not like if they had gotten more from the weapon main room but it was something. They ran to the back door. They are surrounded. 30 seconds left on the time bomb. What could they do?!? Suddently shots come from the woods. They were wookies rescuing them. Once rescued they are taken to the Wookie headquarters. They needed to inform Rex about what they had seen.
