Miners and Scott Guild's Men - a scratch unit holding the silos as the Black Templars advance
Even as the Templars moved on their objectives, a hoard of tyranids, composed mostly of genestealers and gaunts, broke cover, and raced to seize the same objectives which, if held by them, would open the way towards the silos.
Tyranid's break cover
Striking with speed, a Templar skimmer smashed a group of gaunts, which were close to gaining a low ridge which flanked the main approach. The tactical unit The Fist of Dorn moved quickly to hold the ridge, and control the right flank of the battle field. To the left, the Swords of St Clair, carried into battle aboard a razor back, secured a key hill. Between the ridge and the hill was a pile of abandoned storage canisters, a point where the Castallan and the Emperors Champion established a strong point to black tyranid advance.
The heart of the battle: Templar's and Tyranids lock for combat
On the left a broodlord led his retinue of genestealers up onto the hill, and, in a ferocious assault, swept the Swords of St Clair back towards the silos, routing them. The razor back moved to block the tyranid break though, holding the broodlord long enough for the skimmer from the right flank to cross the battle field, and break up the genestealer retinue.
In the centre, the strong point held by the Castallan and the Emperor's Champion was assaulted by a group of genestealers. At the same time a tyranid lictor attempted to infiltrate this position. In a clash of sword and claw first the lictor, then the genstealers were destroyed. This left the Black Templars holding the right and the centre of the battlefield with only scattered resistance on the left.

The Black Templars had secured victory, but narrowly, and with some casualties. The Swords of St Clair all suffered wounds, and carried two of their number dead from the battlefield.
