Concise, well researched and objective; a great homeschool resource
This is a great read; sufficiently detailed to be worth the time spent, but not so bogged down in minutia that you find yourself wondering how long the chapter is going to go on and glancing ahead to see if it ends with a quiz. Particularly notable is the prose: flowing, easy to read, a comfortable narrative. You get a sense of the author relaxed in an easy chair, his audience gathered about, attentive ears regaled with true tales of valor, intrigue, and conquest. But you will find no glorification of war between these covers; rather a well-balanced rendering of man at his best within his worst.
“Great Battles” is well researched, factual, and untainted with retroactive speculation and subjective parochialism that pervade some of today’s ‘historical’ accounts. In short, a valuable addition to any homeschool or military historian’s library; highly recommended.

FINALLY!
Format: Paperback
I was pleased to finally find an historical series written for young boys that neither "cartoonizes" war nor adopts a satirical, demeaning tone. Rather, these books depict the true sacrifices of the men involved in these conflicts. The facts are the facts. There is no politically correct hogwash clouding the child's view of the event. These are more mature historical articles about pivotal events no longer discussed in our public school! These books glorify the ideals scrapped by post-modernists -- bravery, chivalry, and heroism -- ideals that once defined masculinity and limited its so-called "toxicity." As a mother raising masculine gentlemen, I will continue purchasing these fine books! Thanks, Mr. Giorello! Keep writing!
