History's Great Military Blunders and the Lessons They Teach by Gregory S. Aldrete

informative

Don't ignore your experts. They're experts for a reason.
Make sure your intelligence is good - and that you listen to it. See previous point.
Don't change plans at the last second.
Don't assign who is in charge of carrying out said plans at random. 
Don't let politics dictate a plan. 
Make sure you take into account the terrain you'll be fighting on.
Make sure to check the weather.
And, of course, never get involved in a land war in Asia.

A solid selection of military blunders, how they happened, what went wrong and how to avoid them in the future. You've got Market Garden, Gallipoli, Little Big Horn and several others. I like that they weren't all Euro/American-centric. 

Given the topic, this could have been more engaging, but there's still lots of good info here.
