For the first time since the Marine Corps Commandant started publishing an official reading list in 1989, Elbert Hubbard’s “A Message to Garcia” will not be included.

The essay, first published in 1899, tells the story of one American soldier’s journey to relay a message to a Cuban rebel leader before the outbreak of the Spanish-American War. It has long been lauded as a perfect example of strict obedience to given orders no matter the costs.

It was because of this theme that many Marines thought “A Message to Garcia” was outdated. Gunnery Sgt. Joseph Conroy wrote in a February editorial that the essay didn’t promote independence or critical thinking–traits he believes all Marines should possess.

“As leaders of Marines in the 21st century, we are in a unique position to leverage the education, versatility, and intellect of our subordinates,” Conroy wrote. “Rather than shunning questions, we must teach Marines how and when to ask questions and embrace questions through the training and mentoring process in order to eventually deploy Marines who are confident in their leaders, their tactics, and their mission.”

Commandant Gen. Robert Neller removed the essay on the “Commandant’s Choice” section of the reading list after taking over for Gen. Joseph Dunford. His decision was unrelated to Conroy’s article.

So, if “A Message to Garcia” is off the list, what should Marines read instead?

Here are some picks.
