When you drown.... What comes after that?

Harris, Lloyd, quickly dying security horde and not so quickly dying Eniram
horde (plus anyone else not noted)
Blue Dwarf (yet still planet bound and waterlogged), promenade
During one small war
There was the sounding of water splashing, screaming, blades slicing into flesh,
people dying and the sound of one chainsaw hacking scaled bodies into very small
chunks.
"Hail to the king!" The chainsaw welding nutcase of a security yelled as he
swung around and around like a merry-go-round, taking off limbs and the odd head
of any Eniram within distance.
Harris smashed his fist into a Eniram's face and the fishman fell back as there
was a very loud cracking of bone heard. He was covered in blood both red and
green and was well aware of the situation, ammo had been used up and two once
large forces were involved in a very gory melee. Around him he saw some of the
most dirty tactics used by his own men and women in an attempt to drive back the
Eniram and regain control of the promenade. The problem was they were losing,
and losing bad. Only a few of the security were holding their own, Lloyd was
teaching the Eniorams why she came top of the class in marine close combat
training as not only was able to lay a hand on her if she didn't allow it, the
chainsaw welding nutcase was reducing the Eniram numbers, and Tom, Dick and
Harry were making sort work of the Enirams, tearing off limbs and then beating
the limbs' previous owners to death with them.
However, for every Eniram taken down two security were killed. By now two
thirds of the security team that had met the Enirams were now dead. Then it got
worse, Eniram reinforcements.
"Fall back!!" Harris yelled out the noise of the fighting. "Fall back now!"
The security detail began to retreat.
"Harris to whoever's in command." Harris yelled over the ship's internal com.
"Eniram's can not be contained! I repeat, Enirams can not be contained!
Falling back to higher levels!"
