UNITS & FORMATIONS

In the dark waters off Tripoli on February 16th, 1804, a young United States Navy officer, Stephen Decatur, led a small boarding party into one of the most celebrated raids in early naval history. The frigate USS Philadelphia had run aground and been captured months earlier, and Tripolitan forces now held her as a valuable prize in the First Barbary War.

On this day in Philadelphia, delegates of the Continental Congress formally adopted the Declaration of Independence, transforming an armed rebellion into a war for national survival. Fighting had already broken out at Lexington and Concord, Bunker Hill, and along the Canadian frontier, but now the Continental Army, Navy, and Marine forces served an independent United States rather than protesting colonies.

On a July evening in New York, Continental soldiers assembled to hear the newly adopted Declaration of Independence read aloud. Many of these men had been fighting British regulars for more than a year, but this moment tied their service to a clear political break with the Crown. The words about unalienable rights and government by consent took on a sharper meaning for troops who faced invasion from the sea as British forces massed around the city.

A story of a desperate hilltop stand, a fixed bayonet charge, and how it helped turn a Civil War invasion back.

The jungle pressed in on both sides of the Ormoc Road, a narrow ribbon of mud and broken pavement cutting through the hills near Limon on the island of Leyte. December rain had turned the ditches into brown pools. American infantrymen crouched behind a hasty roadblock of felled trees, sandbags, and wrecked vehicles, listening to the grinding approach of steel.

As the Second World War in Europe approached its end, converging Allied armies squeezed the shrinking territory of Nazi Germany from east and west. On April 25th, 1945, elements of the United States 69th Infantry Division, advancing eastward, encountered units of the Soviet 58th Guards Rifle Division near the town of Torgau on the Elbe River. Soldiers from both sides crossed the ruined landscape to shake hands on a destroyed bridge and along the riverbanks.

The winter sky over the Anzio beachhead was a low, gray lid, pressing the sound of guns back down onto the men below. Along a shallow drainage ditch called the Fossa Femminamorta, muddy water slid past tufts of grass and shattered reeds. Somewhere ahead, beyond the next bend, German machine guns covered the open fields that stretched away from the ditch, anchoring a strongpoint that threatened the entire attack.

On August 4th, 1790, the young federal government took a practical step to secure both its finances and its coasts. Responding to proposals from Secretary of the Treasury Alexander Hamilton, Congress authorized the construction of a small fleet of revenue cutters to enforce customs laws and combat smuggling. These fast sailing vessels and their crews patrolled harbors and coastal routes, boarding ships, checking cargoes, and ensuring that customs duties reached the federal treasury.

Almost a year into the Revolutionary War, the siege of Boston had ground on with neither side able to deliver a decisive blow. General George Washington’s Continental troops ringed the city while British regulars and Royal Navy ships held the harbor and town, each side suffering from supply problems and disease.

In the early weeks of the Korean War, United States forces rushed to slow a North Korean advance that threatened to overrun the entire peninsula. Around the city of Taejon, elements of the 24th Infantry Division fought a desperate delaying action, outnumbered and facing tanks and artillery in unfamiliar terrain. Over several days of close combat and street fighting, American troops inflicted significant losses but gradually found themselves cut off and forced to withdraw.

Barely seven weeks after the attack on Pearl Harbor, the first major contingent of American ground troops landed in Northern Ireland. Soldiers from the 34th Infantry Division disembarked in cold, damp weather to the sound of bands and the sight of cheering crowds who knew the war in Europe had entered a new phase. Until then, the British had fought on in the west with limited direct American military presence.

The same date that Marines were struggling ashore on Saipan also saw the debut of a new weapon in the air war over Asia. On June 15th, 1944, Boeing B-29 Superfortress bombers of the United States Army Air Forces flew from forward bases in China to strike industrial targets in Japan in the first mission of its kind.

Four days after the creation of that new engineering district, another milestone unfolded in the skies over occupied Europe on August 17th, 1942. That day, B-17 Flying Fortress bombers of the Eighth Air Force launched the first American heavy bomber raid against a target in occupied France, striking railyards and industrial facilities around Rouen.

Just eight years after the Wright brothers’ first powered flight, naval officers were already asking what airplanes might do for fleets at sea. On January 18th, 1911, civilian pilot Eugene Ely approached the armored cruiser USS Pennsylvania in San Francisco Bay, aiming at a temporary wooden deck built over the ship’s stern.

In early August 1950, the Korean War had entered a precarious phase as North Korean forces pushed United Nations troops back toward the southeastern tip of the peninsula. On August 7th, the First Provisional Marine Brigade, formed from elements of the First Marine Division, arrived at the port of Pusan to reinforce the hard-pressed defenders.

On January 27th, 1943, Eighth Air Force B-17 Flying Fortress crews climbed into icy English skies and headed for the German port of Wilhelmshaven. The mission marked the first all-American heavy bomber raid deep into Germany, part of a growing campaign to hit U-boat bases, shipyards, and industrial centers. The crews flew in daylight formations, relying on tight discipline and concentrated defensive fire to survive fighter attacks.

On February 23rd, 1945, a patrol from the 28th Marine Regiment climbed Mount Suribachi, the volcanic peak dominating the southern end of Iwo Jima, and raised an American flag. A larger flag soon replaced the first, and an Associated Press photographer captured the moment that would become one of the most reproduced images in military history.

More than half a century later, another presidency faced the task of closing a different conflict. On August 20th, 1866, President Andrew Johnson issued a formal proclamation declaring that the insurrection in the former Confederate states was at an end, effectively marking the official conclusion of the Civil War. The great campaigns and bloody battles were already over, but this act drew a legal line under four years of rebellion and set the context for Reconstruction.

As the world edged closer to global conflict, American leaders recognized that citizen-soldiers and long-service professionals alike would need support far beyond rifles and rations. On February 4th, 1941, several existing civilian welfare organizations joined together under a new umbrella: the United Service Organizations, or USO.

The ramps drop into waist-deep surf and chaos. It is the morning of October 20, 1944, on a stretch of shoreline the maps call Red Beach. Ahead lies a narrow band of sand, beyond it a low palm grove and flooded rice paddies. Somewhere in that green fringe, Japanese guns have the approaches bracketed. As the first waves of soldiers tried to cross, the beach turned into a killing ground.

High over Europe on Christmas Eve 1944, the sky is crowded with contrails. Hundreds upon hundreds of heavy bombers push east toward German airfields, the engines’ steady thunder mixing with clipped radio calls. At their head is a single Flying Fortress, the air commander’s ship, where Brigadier General Frederick Walker Castle studies the instruments and the grey cloud deck below.

The rain-soaked hills of Leyte were already torn open by days of fighting when Company A of the 306th Infantry pushed forward against a Japanese strongpoint that refused to break. Machine guns were dug into the slopes, firing down narrow approaches that funneled every American movement into sheets of bullets. A light tank inched ahead, meant to crack the defenses, but the infantry platoon walking behind it stalled under the storm of fire.

The fields near Anzio were bare and unforgiving—flat, freshly plowed earth broken only by shallow furrows and a few low dikes. On a May morning in 1944, Staff Sergeant George John Hall lay pressed into that thin cover with the rest of his company, the dirt shaking under the hammering of German machine guns. Every time a man tried to crawl forward, grazing fire stitched the ground in front of him. Sniper rounds cracked overhead.

Night on Iwo Jima never really felt dark. The sky glowed faintly from flares and burning wreckage, and the volcanic ash underfoot seemed to swallow every step. In a shallow foxhole—a rough, shoulder-deep fighting position scraped into that ash—Private George Phillips stood watch while the rest of his squad finally slept. They had spent the night trading grenades and rifle fire with Japanese troops slipping through the lines.
