Sense Sonnet - Chiller

Under Attack

They came - invaders in my walls,
Picking their spots from which to fight.
My forces were on constant calls
To minimize their awesome might.
Uneasy peace many a year.
They would attack just now and then.
My mercenaries would appear,
And send them back to wait again.
But they were patient ever so.
I weakened as the time went by.
Slowly my defenses did go.
'Twas just the way, no matter why.

Bacteria throughout me spread.
They won, I lost - cuz I am dead.
