For this battle, Hena and I faced off. He took command of rebel xenophilic Imperial Guard, while I dispatched an Ordo Xenos airborne strike force to destroy them as an example of those who traffic with aliens.

Deployment:
Hena deployed in the lower right corner of the board. The sentinels deployed on overwatch as a garrison (interestingly garrisoning his blitz, in his deployment zone). All Inquisitorial forces started off-board in aircraft.
Turn 1:
The Guard won initiative, unsurprisingly putting their thunderbolts on CAP.
(1) One Deathwatch Thunderhawk swung round, strafing with superior turbolaser range the leman russ formation, destroying the hydra.
(2) The second Thunderhawk pulls the same trick on the hydra formation, destroying one and breaking the remainder. Deathshrieks move in to strafe the leman russ, blowing one away with lascannon fire. The russ marshal as a response.
(3) The Aquila bombers made a strafing run against the infantry company, and the Thunderbolts moved to intercept. The Thunderbolts shot down the Inquisitor Lord’s aircraft (there must be a heretic feeding the enemy information! Purges will be made after the battle!). My supreme commander went down in flames!
(4) The second Deathshriek formation activated, sweeping behind and blowing the thunderhawks effortlessly out of the sky.
(5) Both gun-cutters strafed the infantry co. with minimal impact, and picked up BM for exiting on his table edge.
Turn 2:
(1) A Thunderhawk strafed again against the hydra, taking a point of damage in return for a burning hydra.
(2) The mechanised guard infantry with the commander doubled forward along with the superheavies.
(3) and (4) The deathshrieks strafed the Bombards and the manticores, breaking the former but failing to hurt the latter. The Aquila failed to activate and stood down while the sentinels went on overwatch again. The rough riders trotted forward ahead of the mech infantry.
(5) A gun-cutter braved flak (taking a point of damage) and guns down two stands of riders, breaking the formation. The other gun-cutter stood down.
(6) Thunderhawk with librarian landed, assaulting the mech infantry in the open. The firefight destroyed three chimera with armour-piercing bolter rounds but massed autocannon fire blew up the thunderhawk and a Kill Team.

(7) Thanks to the commissar, the Marines broke and ran, hiding behind ruins.
(8) Russes road march and the aircraft disengage. The Marines rally (annoyingly, TSKNF actually hurts me here, leaving a BM where a normal formation would have had none!) and a deathshriek was shot down by hydra fire.
Turn 3
(1) The Deathwatch reassess the situation, and, confident that the previous outcome was a fluke, charged against the infantry co again. Due to some devious countercharging by Hena, 5 guard units fought against one Kill Team, but despite lighting the area up with tracer fire, no casualties were made. Thanks (again) to the Commissar – and that blasted blast marker, thanks very much TSKNF! – the Marines retreated again into woods. The guard company were unperturbed by the Space Marines’ guerrilla tactics.
At this point I made a horrible, horrible mistake. This wasn’t the first mistake of the game – I made many – but it was a real howler. I decided that to prevent the guard from covering the board with overwatch, I should try and keep the pressure on (which was dumb in and of itself, he couldn’t afford to do that as he needed to take objectives!), I also forgot about the -1 for retaining. Of course I rolled a “1â€Â
