The Untold Story

Without Spain, Britain Wins

How Spain and Bernardo de Gálvez Helped Win the War for American Independence

Step into the forgotten global struggle behind America’s fight for independence. Without Spain, Britain Wins reveals how Spanish money, weapons, soldiers, sailors, and strategic victories helped weaken the British Empire when the American cause was at its most vulnerable.

From secret supply routes through New Orleans and the Mississippi to Bernardo de Gálvez’s victories at Baton Rouge, Mobile, and Pensacola, this book uncovers the decisive role Spain played across the Gulf Coast, the Caribbean, Gibraltar, and the seas beyond America. Presented as a courtroom case, the evidence challenges the traditional story of the Revolution and places the reader in the jury box.

This is more than a military history. It is the restoration of the Hispanic soldiers, financiers, sailors, and free people of color whose courage and sacrifice helped make American independence possible.

“Take Spain out of the war, and the American Revolution is lost.”

Can One Forgotten Ally Change Everything We Know About America’s Independence?

In Without Spain, Britain Wins: How Spain and Bernardo de Gálvez Helped Win the War for American Independence, retired Army colonel, prosecutor, and military judge Steve Castlen puts history on trial to examine a question too often ignored: could the American Revolution have succeeded without Spain? Moving beyond the familiar story of French assistance, this compelling investigation reveals how Spanish money, weapons, soldiers, sailors, and strategic victories weakened Britain across a truly global war. From the secret supply routes through New Orleans and the Mississippi to Bernardo de Gálvez’s daring Gulf Coast campaign, the Great Siege of Gibraltar, and the Havana silver that helped secure victory at Yorktown, Castlen presents the evidence as a courtroom case and places the reader in the jury box. The verdict is powerful: without Spain’s courage, resources, and sacrifice, Britain may have won—and the United States as we know it might never have existed.
