Brown-water navy
History: 

River Thames: The River Thames was a regular thoroughfare for the Sovereign until the middle of the 19th century. Monarchs would be rowed up and down the river in a Royal barge, with transport and security organised by the King's Bargemaster. The barges were operated by the Royal Watermen, drawn from the ranks of the Company of Watermen and Lightermen. In 1798, Watermen and other groups of river tradesmen on the River Thames voluntarily formed associations of River Fencibles. These were officially drawn together in 1803 as the "Corps of River Fencibles of the City of London". Members of the Corps escorted the barge carrying the body of Lord Nelson along the Thames in small boats during his state funeral in 1806. The Corps of River Fencibles was eventually disbanded in 1813.

Habsburg and Ottoman Empires: Both the Habsburg Empire and the Ottoman Empire maintained river flotillas on the Danube in 18th and 19th centuries, most notable for the use of šajka boats.
Men who served in the Habsburg flotilla were known as Šajkaši.

Napoleonic Wars: After losing its blue-water fleet in the Battle of Copenhagen in 1807, the kingdom of Denmark-Norway quickly built a brown-water navy. The partial successes of the resulting Gunboat War were undone by land invasion.

Mexican–American War: During the Mexican–American War, Commodore Matthew C. Perry decided to invade the Mexican towns along the Gulf Coast near Tabasco. In October 1846 Perry was in command of USS Mississippi, USS Vixen, USRC McLane, USS Reefer, USS Bonito, USS Nonata and USRC Forward with a 253-man landing force. After capturing the port of Frontera on the Tabasco River, the ships under Perry's command crossed the bar at the mouth of the river and traveled 74 miles (119 km) up river to the town of Tabasco. After several days of bombardment of Tabasco, Perry's ships captured several Mexican ships on the river and brought them back to Frontera. Some were commissioned into U.S. Navy service and others were burned.
The city of Tampico was poorly defended and offered a base for operations for the conquest of the state of Tamaulipas. For these reasons Tampico became the next target for seizure by American naval forces. Commodore David Conner directed that it be attacked in late October 1846 and those plans were captured by General Antonio López de Santa Anna. Santa Anna directed that Tampico be almost abandoned and his forces be moved up river to Pánuco. This move was completed by 28 October. The bar at the mouth of the Pánuco River was only eight feet and hindered the movement of American ships up the river. The wife of the former American consul at Tampico sent word to Conner that the river was rising and that the town had been abandoned. Conner's forces crossed the bar on 14 November and began shelling the town. Almost immediately the remaining garrison at Tampico surrendered and Conner learned that the troops stationed there had retreated to Pánuco 25 miles upstream from Tampico. After Conner's ships moved to Pánuco and several days of naval bombardment, the Mexican forces at Pánuco surrendered. The American Army quickly occupied Tampico and used it for a staging point for a planned attack on Veracruz.

American Civil War: The U.S. Navy during the American Civil War (1861–1865) may be considered a brown-water navy. As a blueprint for the "strangulation" of the Confederate States of America, Winfield Scott's Anaconda Plan called for a two-pronged approach by first blocking the South's harbors and then pushing along the Mississippi River, effectively cutting the Confederate territory in two while also robbing the South of its main artery of transport. The U.S. Navy was assigned the blockade of the seaports, while a new force of gunboats and river ironclads, together with regular army units, would take, or at least lay siege to, the Confederate forts and cities along the Mississippi. In the early days of the war, U.S. Army built and crewed these boats, with the naval officers commanding them being the only direct connection to the U.S. Navy. By the autumn of 1862, the boats and their mission were transferred to the Department of the Navy. Because of the river's murky brown water, the ships that participated in these Mississippi campaigns were quickly referred to as the brown-water navy, as opposed to the regular U.S. Navy (which was henceforth referred to as the deep-water or blue-water navy).

Paraguayan War: After the end of the American civil war the next major military conflict in the world was the Paraguayan War (1864–1870).  In this the Brazilian brown-water navy, which comprised large ironclads as well as river monitors, had a crucial role.

The natural water highway to the Republic of Paraguay was the River Paraguay but this route was blocked by the formidable Fortress of Humaitá. It comprised a 6,000-foot (1,800 m) line of artillery batteries overlooking a sharp concave bend in the river, at a point where the channel was only 200 yards (180 m) wide. A chain boom could be raised to block the navigation.  The fortress was exceedingly hard to take from the landward side for it was protected by impassible swamp, marsh or lagoons and, where not, by 8 miles (13 km) of trenches with a garrison of 18,000 men. The river was shallow, uncharted and capable of trapping large vessels if the water level should fall. In that environment the greatest threat to shipping was "torpedoes" (nineteenth-century floating naval mines).
Six vessels of the Brazilian ironclad squadron eventually succeeded in dashing past Humaitá in an incident known as the Passage of Humaitá, an event considered as nearly impossible.  Although it could not operate far beyond its military forward base, nevertheless, Brazilian domination of the river meant that Paraguay could no longer resupply the fortress, and eventually it was starved out and captured by the land forces in the Siege of Humaitá.

Even after Humaitá was captured − which took more than two years – the Paraguayans improvised further strongpoints along the river, further delaying the Allies (the Empire of Brazil, the Argentine Republic and the Republic of Uruguay).

U.S. gunboat diplomacy in China: Save for an occasional river patrol boat, the United States' river ironclad navy was all but abolished at the end of the American Civil War. Yet the concept of a river defense force lived on in countries and regions where rivers enabled the U.S. to project its military presence, allowing it to protect its foreign interests abroad. U.S. river boats (gunboats) of the Asiatic Fleet operated in portions of Chinese rivers, sometimes referred to as the "Asiatic Navy" or "China Navy", during the turbulent 1920s, patrolling for insurgents and river pirates. Two of the most notable China gunboats were USS Panay, which was sunk in 1937 by Japanese military aircraft prior to World War II, and USS Wake, which was captured by the Japanese in December 1941. The U.S. Navy of that era used the term for protecting U.S. foreign policy and its citizens abroad "gunboat diplomacy". The U.S. Navy, China gunboat, USS Asheville, was sunk by the Japanese in March 1942.

Second Sino-Japanese War: During the Second Sino-Japanese War, the Manchukuo Imperial Navy served principally to patrol the Sungari, Amur, and Ussuri rivers, support Army operations against Chinese resistance forces, and guard Manchukuo's riverine borders with the Soviet Union. In 1939 the Navy's forces came under the control of the Manchukuo Imperial Army as the River Defence Fleet.

Indochina War: During the First Indochina War, the French Navy created the Dinassaut (naval assault divisions), in 1947, to operate in the waters of the Mekong and Red rivers, conducting search and destroy missions, against communist guerillas and river pirates. They succeeded the river flotillas created in 1945, by the request of General Leclerc. The Dinassaut served until the end of the conflict in 1955, and its concept would be latter adopted by the United States Navy in the Vietnam War.
Ten Dinassauts were created, with five based in Cochinchina and the others in Tonkin. Each one was made of about ten vessels and one Commandos Marine unit. The types of vessels operated by a Dinassaut included LCI, LCT, LCM, LCVP, LCS, LCA, LSSL and fire support vessels.
The role of the Dinassaut was to transport, land and support the infantry, to patrol the watercourses and to assure the supply of the isolated posts.
The sailors that served in the Dinassaut were referred as the "Navy in Khaki", in comparison with the sailors that served in the ocean that were referred as the "Navy in White".
