The dreadnought moved to deal with the Wave Serpent and the remnants of the tactical squad, with the captain, moved closer to the Eldar lines. The Terminators unleashed 10 shots with their storm bolters but only caused a single wound on the farseer. The dreadnought failed to hit the Wave Serpent and the tactical squad failed to find a chink in the Scorpions' armour.
In the Eldar turn, the Banshees disembarked from the stationary Wave Serpent and moved (with their fleet move) to within assault range of the tactical squad. The Wave Serpent swept around the bunker but failed to damage the dreadnought. The farseer doomed the terminator squad and cast guide on the Dire Avengers who opened fire and killed three terminators (if that had been a tyranid brood, they would have been completely wiped out!). In my haste to shoot at the terminators, I forgot to move the Scorpions to within assault range, so they were wasted for another turn!
