Attack on Scanning Station D23

In 19 BBY, a matter of hours after Order 66, AWOL Clone starfighter squadron, Sharp Squadron, led by Jedi Knight Koses Lik-Har and under orders from Jedi Master Jeden Vesal, attacked Scanning Station D23 in the Outer Rim. The attack was an attempt by Vesal and his forces, who had disobeyed Order 66, to ensure the Republic/Empire did not locate their three-cruiser fleet. The attack could be seen as the first engagement of any sort between the Empire and an opposing side, and also one of the first times that two opposing Clone forces engaged in combat. The attack was also controversial among the troopers of Vesal's regiment, the 44th Special Forces Division, who thought it wrong to attack fellow Clones.

The attack on Scanning Station D23 marked a pivotal moment in the aftermath of Order 66, displaying to Palpatine that not only were the Jedi still willing to fight after Order 66, but also that not all of the Clones were entirely obedient. Years later, rumours of the attack began to circulate around the Empire, causing many resistance cells to form, such as the People's Liberty Guild on Toydaria.
