"When romance and history, adventure and fact, are combined in readable style, and the history happens to be a field with which we are not all familiar, but in which we are much interested, a book is produced that will be irresistible to many.... Thrilling adventure is plentiful in these pages, and it has the added interest of its political significance. Written in a pleasant, familiar style, not without sharp and illuminating comment, 'The Glory Seekers' is a book to be read with keen delight by the student of history and the lover of romance."—Des Moines Mail and Times.
"A volume which will find an honorable place among Americana.... Mr. Brown's style is detailed and explicit. He indulges in keen character delineation. He makes these hardy adventurers offer their specious apologies. They cease to be the dim and menacing figures of our national history and become comprehensible, if fatal, figures. The book is one which fills a vacancy in history."—Chicago Tribune.
"His effort has been rather to scrape off the successive coats of whitewash which local historians have liberally applied to the darker side of their deeds, and, while giving the would-be empire builders full credit for their personal bravery and physical prowess, to show forth their ambitions and exploits in their true colors."—New York Tribune.
"A book that reads like a novel.... It is not a story to make 'every American's cheek flush with pride,' but, 'The Glory Seekers' is a strong and vivid depiction of the true history of the Southwest, colored with incident and anecdote, and suffused with the enthusiastic Americanism which the most cynical attitude cannot hide."—Butte Inter Mountain.
"A unique, interesting, and valuable story of the early days of the Southwest, when adventurous spirits tried at various times to establish an empire there. Mr. Brown has made an exhaustive study of his subject, and has the facts, which are presented with a cleverness of narration that makes them most delightful reading."—Pittsburg Dispatch.
"Very unconventional in its style, lively and highly entertaining."—The Churchman.
"The author of this excellent and exceedingly interesting work has made a thorough study of the various efforts to found local governments in Texas, independent of Mexico, at an early day.... He is to be congratulated for his excellent work in this historical summary of events in that great region."—Salt Lake Tribune.
"The work is well done. The narratives are lively and well told, and while not highly important episodes, they are all worth preserving as correctives to the too partial story of the colonial patriots as served up in the usual United States histories, if for nothing else."—New York American.
"The romantic story of conquest is brilliantly told."—Portland Oregonian.
