From February 3rd, 2026 through February 9th, 2026, this edition of “This Week in U.S. Military History” traces a remarkable run of anniversaries where alliances are forged, rivers and islands are seized, and entire theaters of war pivot on hard fighting and hard choices. Across these seven calendar days we see the young United States securing a European partner, Civil War gunboats and infantry opening the heartland, and twentieth century Americans battling through jungle, city streets, and the long logistics chains that kept them supplied. The week also reminds us that military history is not only about battles but about institutions, morale, and the political decisions that send soldiers into harm’s way. From the founding of a support organization for service members to the creation of a modern unified command focused on Africa, each story shows how the nation organizes for war and for deterrence. Taken together, these episodes offer a cross-section of American arms, from wooden sailing ships and ironclads to jet aircraft and joint commands.
Treaty of Alliance with France
In the winter of the American Revolution, diplomats in Paris secured an agreement that transformed the struggle for independence. On February 6th, 1778, the United States and France signed a formal Treaty of Alliance and a companion treaty of commerce, bringing a major European naval and military power openly into the war against Britain. The treaty recognized American independence and committed France to fight until that independence was secured, while the United States pledged not to make a separate peace. For the Continental Army, which had survived on thin supplies and uncertain prospects, French aid meant credit, weapons, uniforms, and the promise of a fleet to challenge British control of the seas. Over the next years, French ships, troops, and money would help shift the balance, culminating in the decisive Yorktown campaign. This alliance marked the moment when a colonial rebellion became part of a global war for empire, and it set a pattern for the coalition politics that have shaped American strategy ever since.
Open the Wiki entryUnion Capture of Fort Henry
During the American Civil War, control of rivers was as important as control of railroads, and Union commanders in the Western Theater understood that geography could be a weapon. On February 6th, 1862, combined Union army and navy forces under Brigadier General Ulysses S. Grant and Flag Officer Andrew Foote attacked Fort Henry on the Tennessee River, a Confederate strongpoint guarding access into the Deep South. Ironclad gunboats led the way, pounding the poorly positioned fort, which sat on low, flood-prone ground that left its defenses vulnerable to rising water and plunging fire. Confederate commanders, recognizing their disadvantage, evacuated most of their infantry toward nearby Fort Donelson, leaving the garrison unable to hold. The quick Union victory opened the Tennessee River as a highway deep into Confederate territory, allowing Federal gunboats to steam south and threaten interior supply lines. Fort Henry’s fall also boosted Grant’s reputation, setting the stage for the larger and bloodier struggle at Fort Donelson later that month and signaling that the Confederacy’s western flank was far from secure.
Open the Wiki entryBattle of Roanoke Island
Just two days after Fort Henry, another Union offensive struck along the Atlantic coast, this time aimed at the intricate waterways of North Carolina. On February 8th, 1862, after a day of fighting that began with naval bombardment and continued with infantry assaults, Union forces under Brigadier General Ambrose Burnside secured Roanoke Island. This low, marshy island sat between the Outer Banks and the mainland, controlling access to the sounds that formed a kind of inland sea used for Confederate commerce, coastal defense, and blockade running. Union gunboats had already battered Confederate batteries, and on the ground Federal troops pushed inland through difficult terrain, flanking and overrunning understrength defensive positions. The island’s capture allowed the Union Navy to dominate Albemarle and Pamlico Sounds, threatening nearby ports and cutting important coastal routes. In the months that followed, this foothold contributed to further Union advances along the Carolina coast and added pressure to Confederate forces already stretched between major fronts, showing how amphibious operations and riverine warfare could shape the wider war.
Open the Wiki entryFounding of the USO
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. This nonprofit partnership brought churches, charities, and civic groups into a coordinated effort to provide recreation, entertainment, and personal services to members of the armed forces. Long before the United States formally entered the Second World War, planners understood that training camps, ports of embarkation, and later overseas bases would be far from home for millions of young Americans. USO clubs, shows, and outreach teams worked to reduce isolation, maintain morale, and remind volunteers and draftees that the communities they left behind had not forgotten them. Over time, the USO became a familiar presence in war zones and garrisons from Europe to the Pacific and beyond. Its creation in early 1941 highlights how the nation mobilized not only factories and shipyards but also social institutions to sustain the human side of military service.
Open the Wiki entrySinking of the Troopship Dorchester
In the frigid, dark waters of the North Atlantic, war at sea often struck suddenly and without mercy. In the early hours of February 3rd, 1943, the American troopship Dorchester, carrying more than nine hundred soldiers, seamen, and civilian workers, was torpedoed by a German submarine while en route to Greenland. The blast knocked out power and communication, and the ship began to list and sink in bitter cold, far from land and under threat of further attack. In the chaos, four Army chaplains representing different faith traditions moved among the men, calming fears, directing them toward lifeboats, and handing out life jackets even after their own had been given away. Survivors later recalled seeing the chaplains praying together on the slanting deck as the Dorchester slipped beneath the waves. Hundreds of lives were lost, but many others were saved by swift rescue efforts from escort vessels and by the discipline drilled into the troops. The Dorchester tragedy captures both the vulnerability of supply and transport lines and the personal courage shown in moments where survival is far from guaranteed.
Open the Wiki entryGuadalcanal Declared Secure
On the far side of the Pacific, another struggle over sea lanes and airfields was drawing to a close. By February 9th, 1943, American commanders were confident enough to declare the island of Guadalcanal secure after months of brutal fighting against Japanese forces. What began in August 1942 as a risky landing to seize an unfinished enemy airstrip had turned into a grinding campaign by land, sea, and air, where both sides committed ships, aircraft, and infantry in repeated offensives and counteroffensives. Marines and soldiers battled jungle, disease, and a determined foe, while the Navy fought night surface actions to keep supply convoys flowing. Japanese high command had already ordered a withdrawal, and covert evacuations over several nights had removed most remaining troops. When American patrols found empty positions and light resistance, it confirmed that the enemy had ceded the island. The declaration that Guadalcanal was secure marked the first major offensive victory for American forces in the Pacific War, shifting the strategic initiative and opening the way for a drive through the Central and Southwest Pacific toward Japan’s defensive perimeter.
Open the Wiki entryAmerican Troops Enter Manila
Two years after Guadalcanal, American forces were fighting their way back into the Philippines, determined to liberate a key Allied nation and reclaim a major strategic hub. On February 3rd, 1945, elements of the United States Sixth Army, advancing from the Lingayen Gulf landings, reached the outskirts of Manila and began pushing into the city. Filipino guerrillas and local residents helped guide units toward key objectives, including internment camps holding civilian prisoners. While some American formations achieved rapid surprise and freed thousands of internees, Japanese defenders elsewhere in the city prepared for a desperate, destructive stand. Manila, with its dense neighborhoods, government buildings, and waterfront, became the scene of fierce urban combat involving infantry assaults, artillery, and armored vehicles. The battle would last for weeks and leave much of the city in ruins, with heavy civilian casualties from shelling, fire, and massacres. The entry into Manila on February 3rd signaled that the campaign for Luzon had reached the enemy’s administrative center, but it also foreshadowed the human and material cost of fighting in a large, populated capital.
Open the Wiki entryYalta Conference Opens
Even as troops fought through Manila’s streets, the political leaders of the major Allied powers gathered thousands of miles away to shape the end of the war and the uneasy peace to follow. On February 4th, 1945, President Franklin D. Roosevelt, Prime Minister Winston Churchill, and General Secretary Joseph Stalin opened the Yalta Conference in the Crimean resort city of the same name. Surrounded by security and staff, the three leaders and their advisers spent days discussing the final offensives against Nazi Germany, the future of Poland and other liberated territories, and the conditions under which the Soviet Union would enter the war against Japan. From the American military perspective, Yalta mattered because it helped coordinate timing and priorities, including agreement that Germany must surrender unconditionally and that occupation zones would be established to administer the defeated Reich. It also laid out principles, however imperfectly applied, for postwar institutions, including a new international organization that would become the United Nations. For soldiers and sailors still in combat, decisions made at Yalta would influence how long and where they fought, and under what political arrangements that sacrifice would eventually be judged.
Open the Wiki entryAttack on Pleiku
Two decades later, in the highlands of South Vietnam, another attack on Americans far from home became a turning point in policy. On February 7th, 1965, Viet Cong forces struck Camp Holloway near Pleiku, a base used by United States Army aviation units and advisors. The assault involved mortar fire and ground infiltrators who damaged aircraft, facilities, and barracks, killing and wounding American personnel. Such attacks were not new, but this incident came at a moment when leaders in Washington were debating how deeply to commit combat power to the conflict. Within days, the administration authorized retaliatory air strikes against North Vietnamese targets, opening a sustained bombing campaign that signaled a move from limited advisory support toward a more direct combat role. For the troops on the ground, Pleiku underlined how vulnerable even seemingly secure installations could be to surprise; for policymakers, it provided a vivid example cited in arguments for escalation. The attack and its aftermath illustrate how specific incidents in the field can accelerate broader strategic decisions, tying a remote base in the Central Highlands to debates in the White House and the Pentagon.
Open the Wiki entryStreet Fighting in Hue
During the Tet Offensive, a coordinated series of attacks launched by North Vietnamese and Viet Cong forces, the ancient imperial city of Hue became one of the most hotly contested urban battlefields of the war. By February 8th, 1968, American Marines and soldiers, together with South Vietnamese units, were fully engaged in a block-by-block struggle to retake neighborhoods and key government sites inside the city. Enemy forces had infiltrated during the opening days of Tet, seizing control of much of Hue and using buildings, courtyards, and fortified positions to resist counterattacks. United States troops, more accustomed to fighting in jungles and rice paddies, adapted to house-to-house clearing operations, employing combined arms with infantry, tanks, and artillery while trying to limit damage to historic structures and civilian areas where possible. Casualties on both sides mounted, and civilians were caught in the crossfire or displaced from their homes. The fierce fighting in Hue, still underway on February 8th, demonstrated the intensity of the Tet Offensive and forced American commanders to refine tactics for urban warfare. It also had a powerful impact on public perception back home, as images and reports underscored the war’s complexity and cost.
Open the Wiki entryCreation of United States Africa Command
In the early twenty-first century, American defense planners adjusted organizational charts to match emerging challenges, including terrorism, fragile states, and competition for influence in new regions. On February 6th, 2007, the Department of Defense announced the creation of United States Africa Command, often abbreviated as AFRICOM, as a unified combatant command responsible for military relations with most nations on the African continent. Previously, responsibility for African countries had been divided among several commands focused on Europe, the Middle East, and the Pacific, which diluted attention and complicated coordination. The new headquarters, built around a relatively small American footprint, emphasized partnership with African militaries, support for peacekeeping and counterterrorism efforts, and coordination with diplomatic and development agencies. For service members assigned to its staff and missions, AFRICOM represented a shift toward preventive engagement and security cooperation rather than large-scale combat deployments. Its establishment in early February 2007 shows how the architecture of American command and control continues to evolve, just as earlier generations created new fleets, air forces, and theater commands to meet the demands of their time.
Open the Wiki entryAcross the Week
Across these seven days of the calendar, the stories range from wooden ships and parchment treaties to helicopters, jet aircraft, and modern joint headquarters. Each event captures a different facet of how the United States prepares for war, fights its battles, and tends to the people who serve. Alliances are made and renewed, as in the agreement with France and the later conference at Yalta, while river forts, Pacific islands, and Asian cities become the testing grounds where plans meet reality. Moments like the sinking of the Dorchester and the street fighting in Hue remind us that courage and loss often unfold far from the headlines. As readers look back on this week in history, they can also think about today’s soldiers, sailors, airmen, Marines, Guardians, and Coast Guardsmen who stand on the far edge of policy decisions made at home. The echoes of these past February days still shape the institutions, commitments, and expectations that surround those who wear the nation’s uniform now.
