Book Review: Blunting the Spear

Robert C. Stern explores the uncertain opening months of the Pacific carrier war

The attack on Pearl Harbor is one of the most familiar moments in American history. The battles of the Coral Sea and Midway that followed have likewise been examined in countless books and documentaries. Far less attention, however, is paid to the dangerous four months between them—a period when American forces were struggling to recover, Japan appeared nearly unstoppable, and neither side yet fully understood how aircraft carriers would transform naval warfare.

That often-overlooked period is the subject of Robert C. Stern’s Blunting the Spear: The Pacific Carrier War from Pearl Harbor to the Doolittle Raid, a detailed account of the Pacific War from December 1941 through April 1942.

Stern begins with an American Navy suddenly confronting a very different war than the one it had anticipated. Japan’s attack on Pearl Harbor had crippled much of the U.S. Pacific Fleet’s battleship strength, while Japanese forces moved rapidly across Southeast Asia and the Pacific. Yet the American aircraft carriers had escaped the attack. What followed was an improvised campaign in which commanders, pilots, and sailors were forced to learn the realities of carrier warfare while fighting it.

That uncertainty is what makes Blunting the Spear particularly interesting. Knowing how the Pacific War ultimately ended can make Japan’s eventual defeat appear inevitable in retrospect. Stern instead returns readers to a moment when nothing about that outcome seemed assured. The Imperial Japanese Navy was experienced, aggressive, and operating with considerable confidence. American commanders were working with limited resources, imperfect intelligence, enormous distances, and tactics that had yet to be tested fully in combat.

The book follows operations across an enormous geographic canvas, including the American carrier raids against the Marshall and Gilbert Islands and actions around Rabaul, Port Darwin, Lae, and Salamaua. Individually, some of these engagements have received relatively little attention compared with the great carrier battles that came later. Taken together, however, they reveal the process through which the U.S. Navy began developing the tactics, experience, and confidence that would soon prove critical.

Stern also keeps the story grounded in the people making decisions under extraordinary pressure. Commanders including Wilson Brown and William “Bull” Halsey emerge as men confronting a form of warfare that was still evolving around them. Their decisions had to account not only for the enemy but also for fuel, distance, incomplete intelligence, aircraft limitations, and the potentially catastrophic consequences of losing one of America’s precious carriers.

Some of the book’s most memorable episodes occur at the individual level. Navy fighter pilot Edward “Butch” O’Hare’s famous defense of the carrier Lexington against approaching Japanese bombers demonstrates just how quickly the fate of a ship—and potentially an entire operation—could turn on the actions of a handful of aviators. Stern also provides the Japanese perspective, including fighter pilot Nagahama Yoshikazu’s combat over Port Darwin, reminding readers that American forces faced highly trained and battle-tested opponents during these opening months.

The narrative ultimately moves toward one of the period’s most audacious operations: the April 1942 Doolittle Raid. The physical damage inflicted on Japan was comparatively modest, but the raid carried significance far beyond the bombs dropped on Tokyo and other targets. Its psychological effect, and the Japanese response to it, helped shape the strategic environment in which the much larger carrier confrontations of 1942 would occur.

This is also where Blunting the Spear makes its strongest contribution. Rather than treating these early operations as disconnected episodes between Pearl Harbor and Midway, Stern places them within the evolution of the carrier war itself. Raids that might otherwise seem like historical footnotes become laboratories in which tactics were tested, commanders gained experience, mistakes were exposed, and the possibilities of naval aviation became increasingly apparent.

Stern is well suited to tell this story. The author of more than twenty books on military and naval history, he has already explored the carrier battles that followed this period. His Scratch One Flattop examines the Battle of the Coral Sea, while Knife’s Edge covers the later carrier battles of the Eastern Solomons and Santa Cruz. Blunting the Spear effectively provides the opening chapter to that larger story.

At 312 pages, supplemented by five maps and 42 black-and-white photographs, the book combines operational detail with a broader strategic narrative. Readers particularly interested in ships, aircraft, tactics, and command decisions will find considerable detail, but the emphasis on personalities and the larger strategic situation keeps the story from becoming simply a chronology of naval movements.

Perhaps the greatest strength of Blunting the Spear is the period Stern has chosen to examine. History naturally gravitates toward decisive battles, but decisive battles rarely emerge from nowhere. Before Coral Sea and Midway came months of experimentation, small victories, setbacks, calculated risks, and lessons learned under fire.

By concentrating on those months, Stern shows the Pacific carrier war being created almost in real time. The U.S. Navy had not yet stopped the Japanese advance, much less begun the long drive across the Pacific. It was simply trying to survive, adapt, and find ways to strike back.

That makes Blunting the Spear more than a prelude to better-known battles. It is the story of how the groundwork for those battles was laid—and how, during one of the darkest periods of the Pacific War, the first tentative efforts to slow Japan’s advance began to change the direction of the conflict.
