The Morning a 1,700-Ton Escort Charged the World’s Largest Battleship: The Stand That Saved the Pacific War

At 6:58 a.m. on October 25, 1944, lookouts aboard the American destroyer escort USS Samuel B. Roberts spotted shapes on the horizon northwest of Samar Island in the Philippines. What emerged from the morning haze was not a patrol group, not cruisers on a distant screen—but a full Japanese surface battle force advancing at speed.

For the sailors aboard the Roberts, this moment marked the collision between naval doctrine and raw reality.

The Roberts displaced just 1,745 tons, carried two 5-inch guns, and had been commissioned less than six months earlier. Her crew of 224 officers and enlisted men had trained to protect convoys from submarines—not to confront the heaviest warships ever built.

Ahead of them sailed Yamato, the largest battleship in history, displacing 72,000 tons and armed with nine 18.1-inch guns capable of striking targets more than 25 miles away. Around her moved cruisers and destroyers forming the Japanese Center Force, a formation of 23 warships carrying a combined displacement exceeding 200,000 tons.

Opposing them were seven American ships, totaling barely 25,000 tons.

The imbalance was historic—and immediately fatal if allowed to unfold.

A Strategic Error and an Unprotected Fleet

Hours earlier, U.S. command believed the Japanese surface fleet had been turned back. Intelligence assessments suggested retreat. That assessment was wrong.

During the night, the Japanese force passed undetected through San Bernardino Strait, slipping directly toward the vulnerable American escort carriers supporting the Leyte Gulf landings. Admiral William Halsey had taken the U.S. fast battleships north, leaving Task Unit Taffy 3 exposed.

The escort carriers were slow, lightly armored, and designed for anti-submarine warfare, not surface combat. If the Japanese reached them, the invasion of the Philippines—and potentially the broader Pacific campaign—could collapse.

Rear Admiral Clifton Sprague, commanding Taffy 3, made a decision that would become legendary.

He ordered his destroyers and destroyer escorts to attack.

Charging a Fleet Built to Destroy You

Lieutenant Commander Robert W. Copeland, captain of the Samuel B. Roberts, informed his crew over the intercom that they were about to engage a vastly superior enemy force. He made no promises of survival. He spoke only of duty.

Below decks, Chief Engineer Lieutenant Lloyd Trowbridge made a choice that violated peacetime engineering limits but matched wartime necessity. He bypassed safety systems to push the ship beyond its rated speed. The Roberts surged forward at nearly 28 knots, well above her design specifications.

Speed was no longer a guideline.
Speed was survival.

As Japanese shells began falling around the ship, Copeland ordered evasive maneuvers while closing the distance required for a torpedo attack. The mathematics were brutal: the Roberts needed to travel miles under fire from ships that could accurately engage targets far beyond her own maximum range.

Yet she pressed on.

Torpedoes Against Titans

The Roberts reached torpedo range of the heavy cruiser Chikuma and launched her Mark 15 torpedoes. Although none detonated, the effect was decisive. Chikuma was forced to turn away, breaking her attack run on the escort carriers.

In naval warfare, forcing an enemy to maneuver can matter as much as sinking them.

Those minutes mattered.

They allowed the escort carriers to escape farther south. They added confusion to Japanese command assessments. And they contributed to a growing misinterpretation that the Japanese were facing full-sized fleet carriers rather than lightly built escorts.

When a 5-Inch Gun Changed the Battle

With torpedoes expended, Copeland ordered his guns to open fire.

The Roberts’ forward 5-inch gun, never intended to duel cruisers, began scoring hits through disciplined fire control and relentless pacing. One shell struck a Japanese cruiser’s superstructure. Another disabled a turret on Tone, temporarily silencing part of her main battery.

These were not lucky shots.
They were the result of training, leadership, and refusal to disengage.

As the battle intensified, Japanese fire increasingly concentrated on the Roberts. She took damage, lost speed, and eventually lost power. Still, her crew continued fighting, maintaining damage control under conditions no manual could fully prepare them for.

A Ship That Would Not Yield

By mid-morning, the Roberts was no longer maneuverable. Fires burned. Compartments flooded. Yet even then, Japanese forces continued to engage her, convinced they were under attack by a much larger American formation.

That misjudgment would shape the outcome of the battle.

Believing they faced fleet carriers and heavy escorts, Japanese commander Vice Admiral Takeo Kurita ultimately ordered a withdrawal. His force had suffered damage, expended ammunition, and lost the initiative.

The invasion fleet survived.

Aftermath and Legacy

The Samuel B. Roberts sank at 9:35 a.m., becoming the deepest-sunk U.S. warship ever discovered. Of her crew, 95 men survived, rescued after days in the water through discipline, leadership, and collective endurance.

The Battle off Samar would later be described as one of the greatest last stands in naval history.

Seven small American ships had turned back a force designed to annihilate them.

Admiral Chester Nimitz called it one of the finest moments in U.S. Navy history.
Historians would later agree that courage, confusion, and audacity had altered the course of the Pacific War.

In 2022, explorers located the wreck of the Samuel B. Roberts more than 22,000 feet below the surface, deeper than the Titanic. She rests upright, silent testimony to a moment when a ship built for escort duty chose instead to confront the impossible.

The story endures not because the Roberts was large or powerful—but because, for one morning in 1944, she refused to behave like a small ship.

She behaved like a decision.
And that decision helped save a war.
