Hour three-Surface of Valnes III defense facility (3 hundred hours Sol Time):

Mclane quickly ran back up the stairs to his command squad. He was out of breath when he reached the top of the stairs and proceeded onto the dark landing. He walked up to the very edge and magnified his optical eyepiece to full magnification. He brushed his hair off his forehead and stared at the incoming tyranids. He saw that the 3 carnifexes had been killed and that the gaunts were being driven back by his defenses. He then switched the view to a digital map that showed the battlefield with small icons representing squads with numbers and statistics over them. So far only 2 Imperial Guardsmen had been lost, both in Beta squad. Suddenly a venom cannon shot hit the wall and exploded. For a second Mclane thought that the entire of Beta squad had been killed, but then he saw that the whole squad was still standing and firing. He wiped his forehead.

Up on the front line Private Lewis Syler was firing of shots from his lasgun like crazy. His squad, (squad gamma) was on the far right hand edge of the wall. Currently they were being pinned down by fire from a brood of termagants. He popped his head out for a second to see a flesh borer beetle shoot by his head and to fire of three lasgun shots. Suddenly a shot arced up from one of the Leman Russ conquerors exploded were the brood of gaunts had been. Lewis pocked his head out from cover again to see that the brood had been eliminated. Suddenly Sgt. Bailer yelled: "Target those genestealers making a run for the gate!" Lewis complied and opened fire on the things. He managed to kill to and soon squad Delta realized what was going on and fired on the genestealers from the other side. Soon the whole brood was gone save 2 who ran back wards away from the gate and were hit by a few stray lasgun shots. Then another brood of termagants charged up the ranks of hormagants, tyranid warriors, and genestealers to stop about 50 yards in front of the wall. They sprayed the area with fleshborer fire and Lewis heard a soldier scream from another part of the wall. Lewis sprayed away at the things but there were just too many. Lewis knew that they would be over whelmed soon.
