Mahan vs Corbett

Mahan and a 'decisive battle'
Is it the case of a boiling kettle?
Blowing a lot of hot steam
About something, that to some,

May natural seem!

Of navies and land wars wrote Corbett
Sometimes sneered at Mahan, and yet
Cherry picked his naval wars to get
His students to read 

The 'Green Pamphlet'

That Mahan was inspired by Jomini
Certainly adds to the acrimony
And drives some of us

Out of our wits, to read 

That Corbett also drew  from Clausewitz

To us who have little choice
Since the greats already rolled their dice
Mutely to their ideas 

We must agree, till we can
Contribute with better pedigree!!
