I remember you.
We were in the same trench on Zavastor IV, firing into the xenos hordes until our lasguns warped from the heat. When they reached our position, we filled the trench with their corpses. At one point my bayonet snapped, and I was reduced to hewing away with my trenching tool, climbing over corpses, ours and theirs, to fell any I could reach. It would have been a glorious death, to fall that day. But by the Emperor's will, we both survived, it seems.
