Chapter I: Ambush on Aragon
"Push forward we've got them on the run." Anakin and Obi-Wan said at the front lines next to his clone soldiers. They were in a large open clearing with tall pine trees on all sides, there were four six legged tanks marching besides the clones firing at the retreating droids who were falling back into a rocky gorge.
"We've got them cornered Master." Anakin said next to Obi-Wan as they deflected red droid fire.
"Something doesn't seem right, intelligence says there were more." Obi-Wan said back swatting away the enemy fire.
Anakin held up his wrist communicator as the "Ahsoka have you encountered resistance?" Anakin asked his Padawan who was in another part of the battlefield chasing down battle droids alongside Captain Rex and her own clone troopers who continuously pushed the battle droids back into the thick woods. Her green and yellow lightsabers made short work of any droids in her path with Rex's keen marksmanship downing droids almost as fast as she could take them out "Skirmishers Master, but the tinies are on the run."
"That's what I like to hear, keep up the good work." Anakin ordered and commended her at the same time. When he saw the droids were backed up behind rocks under the cliff and saw a perfect opportunity.
"Sergeant concentrate fire on the ridge!" Anakin ordered the closest clone trooper officer, the clones pointed their rockets up on the cliff tearing them asunder forcing an avalanche on the remains droids.
Obi-Wan sheathed his lightsaber along with Anakin as they had finished up the rest of the droids "Well that's it then?" Kenobi said.
"We win again and you sound disappointed master?" Anakin said patting his master on the back as they started to walk away toward a few gunships coming to collect the Generals and clones.
"Only why our reports were wrong it's almost as if this was…" Anakin and Obi-Wan shared a look that could kill as Obi-Wan trailed off "A trap."
"INCOMING!" One of the clones shouted as a series of rockets flew out of the tree line taking out the gunships sending the wreckage straight into the main Republic force. From both tree lines erupted a barrage of red blaster fire and mortar fire. One of the tanks was hit by the rockets taking out two of its legs demobilizing it.
The lightsabers were redrawn as the clones got behind their tanks forming a defensive circle "Ahsoka finish up the droids and get back to us, we've been ambushed." Ahsoka heard Anakin order into his communications link to her as the droids finished up the droids.
"Rex rally the men, my Masters in trouble." Ahsoka ordered him "Right away Commander." Captain Rex said turning away to give orders Suddenly Ahsoka heard a tremor through the force and ran up behind him "Look out."
A sharp whistle broke through air ripped through the trees hitting one of the clones in the arm that would have taken Rex out.
"Whoa, thanks Commander." Rex said as the clones got into cover, Ahsoka looked at the clone who had a metal arrow lodged in his arm. He was yelling in pain as one of the clones dragged him behind a fallen line.
"What is that?" One of the clones asked "Looks like an arrow?"
Suddenly the air was filled with the sounds of whistling noises, Ahsoka looked up to see a shower of arrows heading right for them. One of the clones looked out behind cover "I can't see where their shooting fro- ACK" one of the arrows hit the lookout right through the head.
Ahsoka looked at Rex "Pop smoke."
The clones reached under their belts and pulled out smoke grenades throwing them over the trees and rocks they were cowering behind. A series of the cans pins popping open and spraying thick white clouds of smoke covered the area.
"Everyone fall back, fall back." Ahsoka ordered.
Back with Obi-Wan and Anakin, their forces were pinned down and loosing men fast, their last tank exploded from a mortar bombardment and suddenly the enemy fire cease out of the blue.
The clones all looked at one another like the Jedi were all confused and waited for another barrage. "Master?" Anakin asked up against one of the downed tanks for cover, the grass field was torn asunder by the mortars and explosives.
Obi-Wan peaked out from behind cover to see shapes moving in the trees but they weren't droids "What do you see?" Anakin asked.
"Not droids, whoever it is I feel we're about to meet them?" Obi-Wan said and on divine providence the jedi and their valiant troops heard thunderous battle cry's and roars from the trees. They were mixes of shell yelps, screams and roars of less humanoid species. Metal was being banged on the metal like random beats but a heavy unified beat emerged at a strong rhythm that reached into the he core of every clone trooper there.
Anakin and Obi-Wan squeezed their lightsabers "Prepare for close quarters combat- Ahsoka what's your eta?" Anakin asked into his coms.
Ahsoka heard him across the battlefield as she let a clone trooper with an arrow through his back lean on her "We're in full retreat Master, we just got ambushed to definitely not droids."
"Same here, change of plans find a place to hold up things are about to get messy here." Anakin said as he climbed the tank as the enemy emerged from the tree line.
They certainly weren't droids, they were all wearing the same horizon blue uniforms but over them they all had leather harnesses over their chest with an assortment of gray body armor over their chest, shoulders, their helmets had a shaded visor over the eyes, with a smooth top back and went straight down from the visor around the jawline encasing their head entirely. Running out of the trees yelling Anakin could see some of them weren't regular soldiers but heavily armored ones covered in the armor with heavy ammo packs on their backs holding repeating blaster cannons firing at the clones allowing the vanguard to advance with E-5 blasters.
"Open fire!" Anakin ordered as the enemy soldiers charged, among their numbers Anakin spotted one wearing a white and dark blue sash wielding a vibrio sword a commando droid would hold "For Freedom, For the Alliance, For THE GALAXY!"
The vanguard broke their formation letting out their own battle cries the clones were overwhelmed within seconds without any close quarter weapons like the enemy combatants. They were all brandishing vibro swords like the commander along with knives and even some holding tomahawk axes. Anakin and Obi-Wan didn't hesitate to jump right into the fray, the master swordsmen began to cut a swath of severed limbs and broken swords before Anakin's blade found itself locked against the hanger sword of the enemy commander.
"I was looking for you." Anakin growled, "Here I am." The commander said through his helmet mask, the enemy commander began to take his sword in both hands swiping and parrying Anakin's lightsaber before out of nowhere Anakin felt a hard left hook smash him right in the jaw, Anakin recovered and saw welded into his shoulder armor was the Confederacy of Independent Systems insignia.
Anakin staggered back caught off guard by the blow and felt the swords edge slice through his robes and down his back. The Jedi general let out a yell of pain that traveled across the battlefield to Obi-Wan who looked to see Anakin spin back around and blast the commander with a force push that sent the commander into the air. His rocket boots ignited and he flew around for a second before dive bombing Anakin and swinging his sword overhead to knock the lightsaber out of Anakins hand.
He swung his sword down on Anakin who caught the sword with his metal right hand and moved it out of the side.
The commander caught Anakin's lightsaber with his own free hand head butted Anakin knocking him back, Obi-Wan saw his former student in peril and rushed to help him, he force pushed the commander off his feet into his own men. When Obi-Wan got to Anakin he stood up "I didn't need your help."
"You may but we're outnumbered, we need to retreat." Obi-Wan insisted as the melee raged around them. The clones continued to fight valiantly among the enemy soldiers, Anakin scanned the battlefield for his opponent and saw a group of the soldiers rallying around him getting to his feet. The man rose his helmet knocked off to reveal a man with brown hair with shaved sides, an oval face with full lips and wide nose. A scar snaked up the left side of his face and over his brow. He picked up his sword and locked a pair of brown eyes with Obi-Wan who was surprised to see him, a soldier with an eel graphic on his helmet helped him to his feet.
The man reached to his belt and pulled out a flare gun and shot it into the sky, the flares hissing burn was followed by the sounds of flapping bug wings. The clones and jedi looked skyward to see "Geonisans?" Anakin gasped as a swarm of bugs descended on them. They wore the grey and blue attire of the soldiers wielding E-5 blasters shooting into the crowd.
Elsewhere with Ahsoka and Rex they were escaping from the arrows "We need to get out of the forest." Ahsoka told Rex.
Rex looked around and spotted the thicket of trees opening to the right "That way." He pointed, Ahsoka looked behind them and was able to glance their pursuers were using the high tree branches to shoot down from leaping from them and taking aim with bows.
"Everyone run I'll cover you." Ahsoka yelled taking out her lightsabers, "You heard the lady move it!" Rex barked, Ahsoka flew into the trees and saw the enemy.
They were dressed in similar garb as the main force attacking Anakin and Obi-Wan, but instead they had on gray uniforms with green camouflage painted armor on their shoulders, chest, extra armor was on the outside of their thighs with teethed boots to keep on the trees. They wore similar helmets like the men but had ghillie suit hoods around their heads and shoulders with lighter armor focused on their chests, shoulders and legs "My turn." Ahsoka said on the counter attack.
She cut the branches out from beneath their feet or sliced the thinner trees, the falling trees caused chaos among the enemies as Ahsoka watched her men escape. Ahsoka looked like an arrow heading straight forward and she cut it down looking to see one of the archers looking at her arrow knocked against his bow he loosed it right at her and she dodged. He appeared different from the others, as his uniform was slightly darker with a blue sash around his waist, he had red red paint on his helmets front below the visor showing a row of teeth and snout of an animal.
Ahsoka ran at him lightsabers in hand and he loosed more arrows she dodged and deflected. He threw his bow over his shoulder and reached behind his back pulling out a knife and leapt over the branches running toward her, Ahsoka swung her lightsaber at him and he jumped over her cutting her across her exposed back. The move would cost him as he had no place to land, but as he fell he raised his right arm and out of his wrist shot a grapple spike it shot up and hit one of the branches. He pulled himself back up on one of the branches.
Fighting through the pain she gazed over at the archer who drew his bow and loosened another arrow. She jumped out of the way getting behind a tree, looking down she saw Rex was clear of the trees "Rex signal the fleet for a withdrawl." Ahsoka ordered.
"Yes commander." Rex said back.
Ahsoka looked back around the to see the archer was gone and suddenly felt a shadow over her head. The attacker dropped down on top of Ahsoka shattering the branches beneath them till they hit the forest floor, Ahsoka stopped his knife from going straight into her eye. The padawan drove her leg between his leg and knocked him off balance before she rolled over, using the force to get her lightsaber. The archer grabbed his bow and knocked an arrow losing it as Ahsoka got her lightsaber "Die jedi!" he yelled she raised them to cut the arrow but it hit her square in the shoulder.
Looking at the man who shot her, she raised her hand and hit him with a force pus so powerful the trees around him were uprooted by fifteen feet back.
Grabbing her arm she ran out of the woods holding her arm with the arrow in it to Rex and the remainder of her squadron that was decimated as a Republic gunship landed, Rex was already aboard waving her "You can make it Ahsoka!" Rex called out, she reached out to him and she pulled him on as the arrows rained down around them.
Ahsoka was panting from the pain as Rex let a medic tend to her "General Skywalker we're clear."
"Behind you Rex, all forces retreat, I repeat retreat." Anakin ordered his men as the fighting around them continued. Hearing his order the clones broke off fighting and started to run back down the field "Admiral Yuralen we need an extraction now." Anakin said into his comlink.
"That would be a problem Skywalker, a separatist fleet just dropped out of hyperspace, three dreadnougths." Admiral Yuralen said from the bridge of his star destroyer, the Venator had two more next to it with three Providence Class Separatist Dreadnoughts engaging them, clone starfighters engaged Rogue-class fighters with blue paint on their wings showing they were separatists. Anakin looked over at Obi-Wan as they retreated to the sounds of the enemy soldiers cheering.
"It wasn't a request Admiral, get it done." Anakin said running in defeat.
Yuralen heard him "Get a squadron to evacuate our ground forces immediately this battle is lost."
