Hour nine-Surface of Valnes III defense facility (9 hundred hours, Sol Time)

As the eighth hour of fighting came to close, the tyranids were in full retreat. Mclane ran to the wall and ordered the troops off the wall. The space marines had the task of repairing part of the damaged wall. Whatever was out there couldn't be good. He moved the conquerors into positions were all but their turrets and sponsons could be hit. He then sent the wounded into the bunker to be checked out by the facility's medic. The space marines took positions on the wall, and his guardsmen set up a second barricade in front of the conquerors. Once everything was ready, they sat and waited, to face the full furry of the swarm.

The huge and towering creatures began coming closer and closer, with them thousands of gaunts came into view little specks, sprinting ahead of the huge monsters behind them.

"How is this possible? The original force was half this size!" Mclane asked. He zoomed in with his optical eyepiece. The monsters had several large pulsating sacks on their flanks oozing out puss. Suddenly one bust and several new gaunts fell to the ground, covered in a mucus like ooze.

"Sgt Velen, what the are those things?" Mclane asked over the intercom.

"I've never seen them before, sir, I will try to hold the gaunts off so that you can get a clear shot with the Leman Russes," Velen Replied.

"Very well." Mclane said back.

After 15 minutes the first gaunts reached the lake only to be mowed down by bolter fire. As more and more charged, the Stormtroopers on the ridges opened up on them. The conquerors began shooting and guardsmen's' rockets and grenades flew through the air. The gaunts fell one after the other, within 30 seconds the first 5 rows had been blasted into oblivion. The large monsters were getting closer.

"Do not fire on the monsters until they get within 200 ft. of the walls!" Mclane told the tank crew. Mclane saw several guardsmen try to run for the bunkers when they saw the huge monstrosities getting closer, only to be held by others and pushed back to the bunkers. The conquerors began shooting shells bouncing off the thick hide of the monsters. Rockets whizzed into the air exploding right in front of the creatures.

"Aim for the head!" Mclane yelled. As he spoke the conquerors fired again hitting the one of the creature's face. It stumbled back, crushing several gaunts. More rockets zoomed at the creatures, this time with more effectiveness. But still many of the creatures lumbered on. More shots fired into the air hitting the creatures' faces, but still the creatures would not stop.

"Concentrate all your fire on the center creature!" Mclane yelled. 5 seconds later the creature toppled over, its head completely gone. Within minutes the rest of the monsters were taken down. Cheers rose but they were short lived as in the distance another contact was spotted. It was twice as tall as the beasts they had just killed. A bio-titan.

"Fall back! Fall back to the bunker! All forces pull back!" Mclane yelled over the com. They couldn't fight the titan. One-by-one the forces on the wall sprinted down the steps to the bunker. When only the tanks and the Space marines and the Stormtroopers were left outside the door was sealed. Outside the battle raged on. The constant shots from the conquerors and the repeated daka-daka-daka of the space marines' bolters were heard through the thick concrete walls of the bunker. Mclane hoped reinforcements arrived soon.

Six hours after falling back to the bunker the last Space Marine's bolter went silent. Not long after the two tanks blasted into flames and hundreds of pieces flew into the air. The Stormtroopers kept shooting, but already claws scraping at the bunker were clearly heard. The scratching and gnawing became louder and louder until almost nothing could be heard. Soldier aimed their weapons in all directions, but suddenly, the scratching and slashing stopped. After several long minutes several men edged slowly toward the door, their guns raised. They opened the door slowly, light pouring into the bunker. Outside hundreds of gaunts lay dead on the ground. The guardsmen saw hundreds of space marines standing inside the courtyard. The Stromtroopers ran down the hill, were they were picked up by a Thunderhawk, which sped off. More guardsmen stepped outside; gaunt's crunched underneath their heavy boots. Victory, all the guardsmen knew it. Shots flew into the air and cheers and yells rang through the air. Mclane looked out over the plains, relief showing on his face.
