I wrote this for my old Unit just prior to the Wave I release. It's not necessarily canonical, so please enjoy without getting too hung up on the finer details. 
 
The sun dawned red with brightest light
			As it swept o’er the mountain height
Revealing vales and meadows lush
			With fauna and flora flush
 
Then down the slopes to the sparkling pools
			Where it flashed sapphire like the brightest of jewels
A scene so picturesque and still
			Rarely evidenced is such idyll
 
When the morning stillness was broken by
			The sound of metal crashing through
The trees and meadows as man came nigh
			To battle and bleed and despoil such view
 
The mists were just rising from the waters
			As from the trees they emerged,
And formed a ragged battle line
			To repel invading Rotters
 
Twelve Men strong they stood down by the water’s edge
And faced the offending bank
Ready to fight, loth to withdraw
			Willing each to die in his walking tank
 
The silence resettled, its loudness profound
			As no sign of the enemy could be seen
When suddenly resumed the crashing sound,
			And the villains appeared upon the sward so green
 
Each side regarded the other
			As they waited for the order to fight
As the silence resumed the defenders remembered
			The events which led to this sight
 
The Clans were in orbit, ready to invade
			While down below defense preparations were made
But Honor demanded tradition be followed
			Never could it be ignored when it was so hallowed
 
And so, they contacted the defenders
			And offered an exchange of information
To best balance the opposing forces
			And limit the damage done in the contention
 
The Defenders called for volunteers to fight,
			But none stepped forward to combat an enemy so fierce
Until Chief Thunder cried,
			“We will, my Warriors and I!”
 
“Eleven Men are at my back
			To repel the Clanners and make them pack!
Send us to fight; we are unafraid,
			And will stand to the last crimson blade!”
 
“So be it!” replied the Commander,
			“You fight at dawn
O’er on the eastward slope
			Is where the battle lines will be drawn”
 
The Chief then called for volunteers
			To fill the Company he would steer
“Who here stands with me?” He called aloud
			“To do our people Proud?”
 
“Say I!” called the one named Ogre
			“Never have I turned from battle!”
“I too!” shouted Rumble,
			“My Hunchback shall make them tremble!”
 
“And I!” proclaimed Nightmare,
			“They stand not a chance,
To fight Jin-Roh is to court death
			 We shall spit them like a lance!”
 
“Count me in!”
			Called out Ayridynn
“I too shall stand” said BerserX,
			“And turn back the thundering herd!”
 
Others volunteered, one by one
			Until at last Chief’s Brigade was done
“To your Mechs!” he cried
			“And let us turn back the Clanner Tide!”
 
Through the pre-dawn dark, they marched
			Until the eastward slope was attained
Then along the brook they stretched,
			Straining their eyes through the dark, the enemy to glimpse
 
Startled from their reverie
			They listened as they heard Chief speak,
“Greetings foe! Pardon if no welcome I offer you,
			For we will make you this ground rue!”
 
“Come at thee!” Cried the Khan,
			“Spare not one!”
The Clanners charged, sunlight gleaming
			From their BattleMechs as they waded through the water streaming
 
“Have at them!” Called out the Chief
			As he too goaded his machine into the flood
The two lines met in a flowing mass
			As leaking fluids turned the waters red like blood
 
Down descended Thor and Loki,
			Gods of Thunder and Mischief
As their mechanical namesakes
			Wreaked havoc along Jin-Roh’s lines
 
Forth strode the Dire Wolf,
			As through the Wolf Brigade
It sowed destruction
			Its fury refusing to fade
 
Others too battered the Wolves
			As they rallied in the mountain brook
Around their Chief like soldiers by their flag
			To stand their ground to the very last
 
Lightning flashed from arms of steel
			As through the air shrieked metal shrill
The Gauss slug flew as missiles pealed
			And through armor lasers drilled
 
Smoke poured from wounds running deep
			As coolant splashed into the water
Like tears from giants that weep
			And cannot be comforted
 
The battle raged as Mechs did fall,
			Plunging through the water’s funeral pall
Fires raged along the banks and through the trees
			Where once was felt naught but the merest breeze
 
The sun was blotted out by the rising haze
			As both groups fought on in a battle-daze
Champions arose on both sides
			Only to fall again into the flowing tides
 
To the right stood Ogre, in his Banshee frightening
			Holding the line against the god of thunder and lightning
With Mischief flanking his side
			He knew he could not the onslaught abide
 
In a desperate act, he closed the distance
			Firing blasts to cover his charge
Until he reached his foes
			Then he seized each one with a hand
 
“If I go down, so too shall you!” He declared,
			As he started the Mech’s self-destruct
Too late he saw the Adder rear its ugly head
			To fire at Ogre’s cockpit
 
Even as the PPCs flew,
			The Banshee self-destructed
Ripping apart Thor and Loki
			Across the ground their parts it strew
 
The Adder was swallowed alive in flame
			The fires of Ogre’s sacrifice
The pilot baked within his Mech
			Could not escape
 
Three down, seven to go
			Raged the battle so
To the left stood Rumble
			In a Hunchback jumble
 
He faced a Timber Wolf,
			A BattleMech fierce and feared
His autocannon fired as fast as it could
			But the task was like a lion to beard
 
When through the swirling tide
			Stood Ayridynn by his side
And together they battled the foe
			Until down at last all three would go
 
BerserX was swarmed early at the onset
			His Orion forced to the ground
While lying prone he continued to struggle
			Making the Clans pay dearly for his flesh’s pound
 
At last, few indeed were left erect
			As both sides shattered each other
Both were down to their last two
			And knew that there could only be one Victor
 
Grimly fought on Chief Thunder
			With Nightmare by his side
Faced by the Dire Wolf
			And a fearsome Kodiak
 
Battered was the Chief’s BattleMaster
			As he rallied to make one last effort
When through the comms he heard Nightmare
			“Et venient luporum loquere!”
 
And as he watched, he saw the Nightmare stride forth
			His own BattleMaster wracked with ruin
To close with the enemy Kodiak and Daishi
			And single-handedly slay the Bruin
 
As Nightmare closed with the two,
			The Kodiak raised its claws to strike,
But faster was the Nightmare’s thrust
			As he drove his cannon through the Great Bear’s ravaged hide
 
With his gun in its chest, Nightmare fired
			Refusing to cease until his finger tired
When at last the great bear fell
			It’s fate quite easy to tell
 
Last now stood the Dire Wolf
			Daishi to the Inner Sphere
“Great Death” it towered
			Before the weary Wolves
 
Chief tried to move forward but his hip was ruined
			From a Stormcrow’s Autocannon
Helpless he could only watch
			As the Daishi shifted aim
 
He triggered a shot, his last
			For his ammunition had run dry
Then he speared the fearsome Mech with his Lasers
			Knowing it would not be enough to stop the killing round
 
He closed his eyes and held his breath
			Knowing it would be his last
When the tortured sound of metallic death
			Rang out like a shotgun’s blast
 
His eyes blazed open upon a sight
			For there before him was the Nightmare’s Mech
Shielding him from the Clanner’s Bite
			With his own machine’s battered wreck
 
And slowly, so slowly, it fell into the Daishi’s chest
			As its gyro ceased to function
And the Nightmare stole a page from Ogre
			And set his Mech to self-destruction
 
When finally, the blast had silenced
			And the re-echoing cries had quieted
And the fires had burned low along the banks
			While the forest was quenched by summer rains
 
Chief Thunder finally stirred
			Broken from his trance
By the sound of salvage crews arriving
			To strip equipment from the dead’s remains
 
And later, back at base he heard
			The report he feared
“All dead, no survivors,” said the Commander
			“We are grateful for their sacrifices,” He added with candor
 
“What will you do now?” He asked intently
			The Chief stared into the distance
His thoughts upon that harrowing fight
			Until finally he again broke his trance
 
“Now?” he repeated, “Now the Inner Sphere shall know
			That we shall stand strong; Jin-Roh!
To stem the tide of the Clans
			And purge them from our lands”
 
“As Nightmare said before his death,
			 ‘Et venient luporum loquere’
“To that I’ll add, ‘Lupis et Veniet de’”
			“Then all shall know”
 
“They shall speak of the Wolves and they shall come!”
			His voice rang out
“Upon every field shall be heard our battle shout!”
			“To avenge our fallen and protect our homes”
 
“Now stand we in Mortal Defiance of the Clans!
			“Let them come and die by our hands!
“What happened here shall not be forgotten
			“As long as we endure”
 
“To the Clans I say,
			“Molon Labe!
“And to the Inner Sphere I say
			“Lupis et Veniet de”
 
“I say again, ‘Let them come!’”
