The Most Underrated Military Strategist?

William Sims is one of the most underrated officers and strategists in the history of the United States Navy, and arguably the American military as a whole. Many are, of course, familiar with the writings of Alfred Mahan, the most famous strategist in the history of the United States Navy. Many fewer know that Mahan’s intellectual swan song, so to speak, happened when Sims soundly defeated Mahan in a debate in the pages of Proceedings, a magazine published by the U.S. Naval Institute, over the all-big-gun battleship in 1906.

Throughout his career, Sims made a significant difference in ways that positively influenced the ability of the U.S. Navy to fight and win wars. Early on, Sims, drawing on the ideas of British naval innovator Percy Scott, brought the new continuous fire method, which used an elevating gear and new sights to allow gunners to aim and fire constantly, rather than just as the waves rolled, to the United States Navy. This dramatically improving the ability of the Navy to accurately target and hit enemy ships. Sims then helped lead the charge for the Navy to adopt the best battleship design of the period – the all-big-gun battleship. Eliminating smaller-caliber guns and switching to all-large-caliber guns meant these battleships offered navies significantly greater striking power than the previous generation of ships. The U.S. Navy’s rapid adoption of modern battleship design helped it keep pace with the British and Germans and continue its rise in the early 20th century. Sent to lead American naval forces in Great Britain in World War I, Sims excelled at the task and then wrote a Pulitzer Prize-winning book, The Victory at Sea, about the Allied response to the U-boat campaign during the war. Finally, Sims led the Naval War College from 1919 until he retired in 1922, reforming its educational practices in ways that encouraged experimentation and tabletop gaming. These reforms created intellectual space for a generation of naval officers such as Chester Nimitz to figure out the best way to use new capabilities such as naval aviation and the submarine. It is no wonder that, at the time, Sims was considered a great innovator and naval leader.

In his new book, 21st Century Sims, USN Lieutenant Commander Benjamin F. Armstrong introduces this largely forgotten strategist to a new generation. In an accessible volume that builds on his prior work on Mahan, Armstrong introduces Sims to the reader, and then intersperses commentary with original writing from Sims for the rest of the book. This smart choice not only gives readers context to understand Sims’ ideas in their own time, along with potential applications today, but also lets Sims speak for himself.

This is an important book. Sims’ ideas, as explained below, and by Armstrong, are highly relevant for the challenges the U.S. military in general, and the Navy in particular, face today. Sims’ focus on military innovation, in particular, can both provide context for key strategy choices by the Navy in the early 20th century and useful insight and inspiration for future naval leaders seeking responsible ways to ensure that the U.S. Navy remains ahead.

Armstrong gives readers access to six of Sims’ written works:

  • A 1906 article, featuring part of his debate with Mahan about battleship design. In it, Sims explains how the then-revolutionary shift to an all-big-gun design would maximize firepower without sacrificing efficiency.
  • A 1916 speech on military character, in which Sims discusses the importance of both loyalty and initiative in the mindset of the modern soldier.
  • A 1919 speech to students at the Naval War College, laying out his vision for how the Naval War College could shape the future of the U.S. Navy. This important speech made a strong argument for war-gaming as a necessary part of naval training.
  • A 1921 speech to the graduating class of the Naval War College, focused on conservatism and risk aversion within the Navy. The backdrop for this speech was the introduction of the submarine and airplane into naval warfare. Sims explains, in this speech, the natural tendency towards more proven capabilities, as opposed to investing in new capabilities. Sims explains that the U.S. Navy has been slow to adopt even inventions first debuted in the United States, and that this conservatism risks weighing the Navy down. He advocates for both experimentation, and the courage to follow through and implement what experimentation suggests actually works.
  • A 1922 speech to Naval War College graduates that addressed the responsibility of the Navy in the broader context of decisions about budgets and strategy. He focused on how, despite post-war demobilization, the Navy could still have the capacity to protect the country, given how it had succeeded in more difficult situations in the past.
  • A 1934 article, written after his retirement, focused on the military promotion system. Sims critiques the naval promotion system of the time, arguing that promotion boards often lack the key information necessary to make optimal promotion decisions. Recognizing that no system will be perfect, Sims advocates for a system where admirals throughout the fleet would vote on promotions, rather than just the narrower board.

Readers also will appreciate an article about Sims published a year after his death in 1936, written by Captain Harry Balbridge. Balbridge describes Sims as an “iconoclast,” focusing mostly on Sims’ intense efforts, as a junior officer facing strong career incentives to keep quiet, to reveal the Navy’s struggles with gunnery and design a new and improved system.

Armstrong’s commentary throughout the book is striking, well-written, and offers many relevant insights into critical issues facing the U.S. military today. In some ways, the book leaves the reader wanting to hear more about Armstrong’s own perspective. The advantage of this approach, as referenced above, is that it lets Sims speak for himself. Given that this is the primary purpose of the book, it accomplishes its mission extremely well. However, while the introductory essay is extremely useful, as are the introductions to each chapter, it would have been interesting to hear more from Armstrong at the end of the book about which of Sims’ lessons he views as most relevant for the U.S. Navy today. Perhaps this could be the subject of a future article or essay at War on the Rocks.

This book is highly recommended not just for those interested in naval strategy, but those interested in military strategy, military innovation, and civil-military relations more broadly. Sims occupies a unique place in history. He not only served in the U.S. Navy prior to the Spanish-American War, the conflict that demonstrated that the Navy had come of age on a global stage. He also served into the era of the airplane, where his writings directly shaped some of America’s most important future naval leaders, and he helped set in motion the war gaming and experimentation that led to America’s mastery of carrier warfare, one of the single greatest successes, from an innovation adoption perspective, in the history of naval warfare.
