The Empire accused the citizens of Tondatha, a small town on Agamar, of being members of the resistance and collaborating with the Rebel Alliance. To send a message to the population of Agamar, the Empire destroyed Tondatha with an orbital bombardment. The event persuaded survivors, including Keyan Farlander to join the Resistance.
The Resistance held frequent clandestine meetings, discussing their opposition to the Empire, but most of them found it hard to believe that they could stop the Empire. That changed several months after the attack on Tondatha when Mon Mothma visited Agamar in order to persuade the Resistance to formally become part of the Alliance. The Rebels held a rally in an abandoned warehouse attended by around 200 dissidents. Security for the rally was tight, the whole area was shielded, picket droids were deployed and the Mon Calamari Star Cruiser Independence was in orbit of the planet. Following the rally, Mon Mothma met with the leaders of the Resistance and several members of the Resistance left Agamar to enter service in the Alliance Military.
