Good morning, good morning
The General said
As we met him last week on our way to the line
Now the men that he spoke to
Are most of them dead
And we're cursing his staff for incompetent swine

He's a cheery old soul
Said Harry to Jack
As they slogged up to Arras
With Rifle and pack

But he did for them both, by his plan of attack


Sigfried Sassoon (I think, from memory)
