The Argos was on its route in the inner circle of the galaxy. The ship converted into an intelligence center in space was a hive of reports; the attacks by Jahve's pirate fleet were a success; those guys barely rested between one attack and another; the enemy's supply lines were really screwed; when the attack was not on the ships in the systems, it was on the convoys they were sending out.
Also, the effect of the attacks of the new enemy ships was mitigated since the attack on Seican 12, this operation had been repeated up to three more times over the last two months, there were 2 other attempts, but several of the new powerful Enemy ships were waiting, in the end the operations were aborted after a small scuffle.
There had not been a return to stagnation; systems were lost and retaken, but much more slowly, the enemy elite forces now had a triple mission: defend the systems won from the humans, protect the convoy routes, and attack when they saw a chance.
