The other Marines had a similar set up with fewer brothers in squads, and an Assault squad led by a Chaplain.  Overall command was given to a Master on his side of the board.

Necrons had 4 groups of Warriors, 3 Destroyers, 2 heavy destroyers and Lords with veil of darkness and orbs.  The Warriors ranged from 16 to 20 troops each.

We had moderate terrain, with 2 large buildings between us and a few hills.

The Necrons, curse their metallic souls, got the first move and proceeded to blow Dora to bits.  The remainder of the troops moved forward.  Their other fire was ineffective. 

A general advance was ordered for the tactical squads.  Brother Lucian attached himself to the first squad.  The devastators fired into a group of warriors, downing several but with 1 brother exploding in a shower of plasma.  Lucian launched a warp being into several groups of warriors, causing a few of the warriors to drop.  They failed their leadership test and fell silent!  Praise to the Emperor!

A heavy destroyer went down to the other Marines, and their rockets found another group of Necrons.  They too failed leadership and fell asleep.

Then the first Necron Lord leapt into the fray, throwing a veil of darkness across the board.  In an instant a group of warriors appeared next to both of the devastator squads and the remaining Whirlwind.  Praise to the dice gods as several gauss shots struck the Whirlwind by failed to do anything more than stun the crew.  The pinned groups did weapon checks and made gruesome faces at the opposing Marines.  The final group advanced on the flank.

Crassis rounded a building and found the Necrons making rude gestures.  Assault cannon and storm bolter blazing cut them down.  Then he charged into their midst.  The warriors beat on his armor to no effect.  His laughter could be heard as he rampaged amongst them.  The devastators, finding warriors so close at hand laid into them.  The other Marines, including the assault squad also lent their firepower.  Then the Assault Marines charged.  The warriors were swept away after failing another leadership test.  Lucian called upon the power of the warp, subjecting the warriors to fear the darkness.  The results were ineffective.

Now the second Lord dropped his warriors on the opposite of the board.  The forces in front of my Dark Angels were locked in combat with Crassis or falling back. 

The advance continued, even the Devastators moved forward.  The first squad finished off the destroyers.  The Necron lost in their battle with Crassis, who swept their remains from the table.  The battle raged on the left, the loyal Marines taking heavy losses.  But another group of warriors fell to the Assault Marines.

Alas, Crassis fell to the heavy destroyer in a spectacular explosion.  With no other Necron to face the advance continued.  The remaining Necron phased out the next turn.
