Tau commander Moonshine had made the initial landings on Sartano and unlocked the door to the south, but it would be Strongspear's forces, in late 05.010M42 far more numerous than Moonshine's, who would be expected to continue the advance. Once Strongspear's cadres had moved through those of Moonshine, the newer commander withdrew back to Tuva and Strongspear's forces began moving further inland, heading for the industrial capital of Sartano.
Strongspear's forces were highly mechanised and covered ground quickly. The main Imperial strongpoint lay ahead, where the jungle and wetlands of the coastal region gave way to a wide river valley where factories stretched from horizon to horizon. If they were allowed to get into the built up industrial zone, the Imperium would have trouble shifting them, so Cunningham sent in COlonel Moore's Prozan 7th cavalry at the vital crossroads of Farinelli.
Strongspear's armoured spearhead was making its way straight towards the vital strategic objective of Farinelli, and at first only a few units of scouting strom troopers were encountered. The Tau easily dealt with these and the sporadic artillery which was being launched, rather speculatively, from the industrial zone in the valley below Farinelli. However, at 0900 on 3105.010M42 the Prozan cavalry arrived, determined to ensure the Tau did not break through to the Sartano industrial zone.
The Prozans faced difficulties from the start as their Vulture gunships were caught at long range by Hammerheads as they dealt with infiltrating Tau stealth suits. Most were disabled or destroyed. Next a wave of Vendetta gunships raced into the heart of Strongspear's formations, opening up and annihilating the Tau hammerhead tanks but facing the entirety of Strongspear's firepower. Their retribution was swift and the entire wave of Vendettas was lost. The Tau were now without tanks support, but were still moving closer to the crossroads.As night approached the remainder of the Prozan regiment arrived, moving their Valkyrie transports directly to the vital objectives of the town. There they hunkered down and blew apart any Tau forces which attempted to break into the settlement. The Tau had been stopped. Over the next few days. with the Tau pinned at Farinelli, General Cunningham was able to outflank Strongspear on both sides, and the 7th Prozan Cavalry, despite taking heavy casualties, were involved once more. The regiment had its first victory over the Tau and Strongspear, frustrated, was force to abandon Sartano and the hard won gains made by Moonshine just days earlier.
