In the Service of Two Kings

In the service of two kings,
I fight bravely in two wars, 
I swing my blade, 
From atop my horse, 
And cut men down and enforce, 

The simple men,
who have a side,
which, perhaps if they knew as well, 
the truth behind the battle, 
is that no real quarrel fell,  

but a plan of humorous grandeur, 
the absent cowards play, 
for which men, such as us, 
are those who invariably pay.
