Duncan sensibly split the objectives in my half to be as far apart as feasibly possible (6 feet away from each other, on the centre line). My objectives were on the centre line directly in front of my own blitz. What looks suspiciously like deth koptas are my sentinels (because I don't currently own 12 of them) - 2 units were garrisonned forwards on one obective, with the warhounds both hiding behind buildings. The warlord and imperator were deployed on my blitz, with a unit of sentinels lurking in the wood near the blitz.
Turn 1:
Titans win the Intiative.
-The imperator moves first, singleing forward, and kills the only things it can see (1 valk, 2 ig). from air cav (1)
-Lightnings fail to activate
-My sentinels (1) near the blitz move into the woods near my own blitz
-Lightnings strafe sentinels (2) who are nearest objective on far left, causing a BM
-Sentinels (2) choose to marshal and move into wood. 2 1's mean a dead sentinel from a walker test (doh!)
-Marauders fail to activate
-Sentinels (3) double to get behind the buildings nearer to the centre
-vanaheim sentinels double up into the wood on the far left, stop exactly 10cm away and put a BM on sentinels (2)
-Warhound 1 moves up, kills one of the vanaheim sentinels in the wood (only one in range/los) as they're only available target
-Vanaheim second unit of sentinels double up and shoot at sentinels (3) putting a BM on them
-Warhound (2) rounds corner, wipes out second unit of vanaheim sentinels
-vultures (1) form a conga line and get 7 hits on warhound (1), leaving it on 1HP
-warlord doubles, kills 1 valkerie from air cav (2) as it's the only thing in range/los
-vultures (2) form a conga line and get 7 hits on warhound (2) killing it
-SC air cav moves up to behind buildings near centre right hand side
-Storm troopers march up to broken warhound (1) stopping 15cm away
-air cav (2) shoot at sentinels (3) killing 2 of them and breaking them
-air cav (1) moves to occupy woods in own deployment zone, staying more than 10cm from edge of wood.
End of turn, planes leave enemy board edge, taking a BM each. Everything broken rallies (even though near enemy)


Turn 2:
Vanaheim win Initiative
-Storm troopers assault warhound (1). Fail to kill it, but take no casualties in return. Warhound (1) hides behind buildings.
-lightnings retain, fly through Imperators flak losing one, but kill off warhound (1)
-warlord doubles to get los on air cav (2). spectacular failed dice result in 1 valkerie dying (volcano cannoned)
-air cav (2) moves to behind sentinels (2), break them and they retreat through the narrowest margin along the board edge
-lightnings retain, break sentinels (3) - rolled loads of 6's for armour, but have enough BM's to break anyway
-Imperator doubles to contest middle 2 objectives, shoots vultures (2) killing 2. vultures (2) break and fly off to the objective on far right.
-SC unit doubles to my blitz, shoots at sentinels (1), breaking them. Sentinels (1) retreat to far side of wood.
-Marauders bomb broken sentinels (2), wiping them out.
-air cav (1) fly closer to objective on left but basically bimble about.
-vultures (1) march over to far left side, hide behind buildings
-vanaheim sentinels do nothing over by far left objective just stand around in the wood contesting the objective.
End of turn, everything rallies, planes fly off.


Turn 3:
Titans win Initiative
-Imperator turns around, shoots up SC air cav, breaking them. They choose to remain loitering near my blitz.
-Sentinels (1) retain and assault broken SC unit (which has roughly 50% of models remaining). Sentinels kick massive ass with 2 kills in return for the loss of 1 sentinel. A roll of 5 vs a roll of 3 means I win by 1, wiping out the SC unit apart from the commissar (fearless)
-air cav (2) shoot up sentinels (3) killing them with significant overkill
-warlord shooting vultures (2) killing 1 and breaking them so they aren't contesting the far right objective
-vulture (1) move to hold objective instead
-storm troopers move onto my blitz.
-air cav (1) move to contest centre objective
End result 2-0 (blitz and another objective) to the vanaheim

I could have forced the game onto turn 4 by marching the imp onto my own blitz, and the warlord marching onto the far left objective (making it 1-0 as he would have all his own objectives instead) But dinner was calling and I wanted to shoot something with the Imperator that wasn't 1 or 2 models.
Things I should have done differently:
-shouldn't have garrissoned my sentinels, and should have kept them within the flak bubble (foolish error on my part by not pre measuring)
-The imp should have just stayed on the blitz, but if it was doing that I would have been better off taking a reaver with quakes
-something with indirect fire was required, everything just hid away and waited till I was out activated before moving out of cover. The indirect fire was needed to flush out enemy units
-The warlord did basically nothing, I should have taken something else instead
-I should have deployed my blitz in a corner and the objectives directly in front of that - forcing the game down a 1ft slice of one edge of the board, and put an artillery titan permantly on it
