Information about Amphibious Warfare

Amphibious warfare is the utilization of naval firepower, logistics and strategy to project military power ashore. In previous eras it stood as the primary method of delivering troops unto non-contiguous enemy-held terrain. Airborne operations have slowly eroded this primacy as larger and more capable air transports have been fielded. In this modern era amphibious warfare persists in the form of commando insertion by fast patrol boats, zodiacs and mini-submersibles. Debatably, states with modest airlift potential may view amphibious operations as a viable means of troop deployment.

In the modern era of warfare, an amphibious landing of infantry troops on a beachhead is the most complex of all military maneuvers. The undertaking requires an intricate coordination of numerous military specialties, including air power, naval gunfire, naval transport, logistical planning, specialized equipment, land warfare, tactics, and extensive training in the nuances of this maneuver for all personnel involved.

An amphibious landing is distinguished from an airborne landing in the following respects: an airborne landing can take place virtually anywhere, while an amphibious landing must occur on a suitable ocean-facing beach; and an airborne landing in most cases must be supported almost exclusively from the air, while an amphibious landing can be supported by both air and naval shipping.

History

Recorded amphibious warfare predates the 18th century by a couple of millennia: the Sea Peoples that menanced the Egyptians from the reign of Akhenaten as captured on the reliefs at Medinet Habu and Karnak, the Helenic city states who routinely resorted to opposed assaults upon each others' shores which they reflected upon in their plays and other expressions of art, the landing at Marathon by the ancient Persians on September 9 490 BC which history records as the largest amphibious operation for 2,400 years until eclipsed by Gallipoli. More current amphibious landings have been conducted by small commando forces of various states and non-state actors; Israel, Tamil Tigers etc. And there exists intense debate over mainland China (PRC)'s potential to conduct amphibious operations against Taiwan (ROC). With the bulk of the world's population concentrated near the sea, chances are good that future conflict may entail the use of amphibious assets.

16th century

In 1565, the island of Malta was invaded by the Turks. A strategic choke point in the Mediterranean Sea, the loss was so menacing for the Western Europe that forces were urgently raised in order to recover the island. But it took four months to set up, arm, embark and move a 5,500 men amphibious force to the area in battle order. Then, Philip II, King of Spain, decided to permanently assign certain already amphibious skilled Units to the Royal Armada. These units were trained specifically for the fighting on ships and from ships. The Spanish Marines were born. The idea was to set up a permanent assignation of land troops to the Royal Spanish Navy, available for the Crown. Thus, countries adopt the idea and all around the world. Countries raise their Marine Corps too.

The first "professional" Marine units were already task-trained amphibious troops, but instead of being disbanded, were kept for the Crown's needs. First actions took place all along the Mediterranean Sea where the Turks and Pirate settlements were a risk for the commerce and navigation: Algiers, Malta, Gelves, La Goleta...

Landings as the "Terceras Landing" in Azores Islands 25 May 1583, was a military feat as the planners decided to make a fake landing to distract the defending forces (5,000 Portuguese, British and French soldiers); also special barges were arranged in order to unload horses and 700 artillery pieces on the beach; special row boats were equipped with small cannons to support the landing boats; special supplies were readied to be unloaded and support the 11,000 men landing force strength. The total strength of the amphibious force, was 15,000 men, including an armada of 90 ships. After an initial reconnaissance action where the most suitable beaches for the landing assets were chosen, a 4,000–man first assault wave was unloaded while two "Galeras" made a distractive fake landing away from the main beach. The main defensive body ran to defend against the feinted action, but the first wave had set up a firm defensive perimeter, and the second wave was already landing with the heavy artillery.

In this operation we can find documented reports about the detailed planning, the previous reconnaissance of the beaches, the special equipment and training, ship-to-shore movement, naval fire support. Not the first landing, but one of the first amphibious operations.

17th century

This was a century of "expansion". European countries were expanding and creating colonies. Amphibious operations were mostly oriented to settle colonies and strong points along the navigational routes. Fights among countries to keep or destroy opposing power's capabilities were continuous.

Amphibious forces were fully organized and devoted to this mission, although the troops not only fought ashore, but on board ships.

18th century

Amphibious landings are performed by Spanish Marines allowing them to conquer Sardinia (1717) and Sicily (1732)

But not all landings were successful. Mere frontal assaults from the sea against well defended positions are to be a fiasco should they be halfhearted planned.

On March 13, 1741, a British fleet, including 2,000 guns in 186 ships commanded by Admiral Sir Edward Vernon, tried to take the Spanish City of Cartagena de Indias with a 23,600–man force. 4,000 Virginia recruits, commanded by Lawrence Washington (half-brother of George Washington), took part in this action.

The defenders lined up 3,000 men, including Marines from the only six ships based in that port.

After 15 days of bombing, the British start the landings, delayed by the defenders' actions, and manage to scuttle the six Spanish ships attempting to close the access channel to the city. The defenders are decimated, and only 600 remain inside the last bastion: San Felipe Fortress.



The Commander of the landing force, General Woork, tried to advance but due to the heavy equipment his forces made only slow progress towards the fortress. The defending artillery focused on the ships supporting troops and the ship-to-shore traffic, while the defenders decimated the advancing troops out in the open. The landing force advance ended abruptly when the attackers found the ladders and engineer equipment was not suitable for the fortress assault.

During that very night a carnage took place among the landing force, and with the first light of the morning, a surprising bayonet charge from the defenders finished the landing force and their supplies.

For 30 more days the attackers bombed the fort with no results, and they fell back to Jamaica.

In 1759, during the siege of Quebec, the British troops attempted on a number of occasions to cross the Saint Lawrence River in force. An attempt to land some 4,000 troops in the face of resistance failed. Ultimately a landing was managed at a relatively-undefended site, and British troops gained a foothold allowing 5,000 to take part in the Battle of the Plains of Abraham which led to the surrender of the city.

In 1776, Samuel Nicholas and the Continental Marines, the "progenitor" of the United States Marine Corps, made a first successful landing in the Battle of Nassau.

In 1781, the Spanish field marshall Bernardo de Gálvez, successfully captured British controlled Fort George by ampibious assault in the Battle of Pensacola. In 1782, he captured the British naval base at New Providence in the Bahamas.

19th century

During the American Civil War, the United States made several amphibious assaults all along the Confederate coastline. Port Royal, South Carolina was the first of many attacks. Along with others on Roanoke Island, NC, Galveston, TX, Morris and James Islands, SC, Fort Sumter, SC, Norfolk, VA, and several others. The largest was at Fort Fisher, which was the largest and most powerful fort in the world at the time, protecting the entrance of Wilmington, North Carolina. The assaulting force of over 15,000 men and 70 warships comprising of over 600 guns, was the most powerful amphibious assault in world history and was not surpassed until D-Day 1944.

An early form of amphibious warfare was employed during the War of the Pacific in 1879, and saw coordination of army, navy and specialized units.

The first amphibious assault of this war took place as 2,100 Chilean troops successfully took Pisagua from 1,200 Peruvian and Bolivian defenders on 2 November 1879. Chilean Navy ships bombarded Allied beach defenses for several hours at dawn, followed by open, oared boats landing Army infantry and sapper units into waist-deep water, under enemy fire. An outnumbered first landing wave fought at the beach; the second and third waves in the following hours were able to overcome resistance and move inland. By the end of the day, an expeditionary army of 10,000 had disembarked at the captured port.

Additional amphibious assaults would be carried out thorough the war. By early 1881, Chilean commanders were using purpose-built, flat-bottomed landing craft that would deliver troops in shallow water closer to the beach.

Landing tactics and operations were closely observed by neutral parties during the war: two Royal Navy ships monitored the Battle of Pisagua; U.S. Navy observer Lt. Theodorus B.M. Mason included an account on his report The War on the Pacific Coast of South America.

World War I

During World War I, amphibious warfare was still in its infancy: tactics and equipment were rudimentary and required much improvisation.

During this period, British Royal Marine Light Infantry (merged with the Royal Marine Artillery in the 1920s to form the Royal Marines) were used primarily as naval parties onboard Royal Navy warships to maintain discipline and man ships' guns. The RMLI joined a new Royal Navy division—the Royal Naval Division—formed in 1914 to fight on land; however, throughout the conflict, army units were depended upon to provide the bulk—if not all—of troops used in amphibious landings.

The first amphibious assault of the war ended in disaster in 1914. A large British Indian Army force was directed to launch an amphibious assault on Tanga, German East Africa. British actions prior to the assault, however, alerted the Germans to prepare to repel an invasion. The Indian forces suffered heavy casualties when they advanced on the city, forcing them to withdraw back to their boats, leaving much of their equipment behind.

The Allied invasion against the Ottoman Empire at the Battle of Gallipoli in 1915 proved even more disastrous than Tanga, in part due to incompetence at the high command.

Soldiers were landed via open, oared whaleboats and tugs at Anzac Cove and Helles. At V Beach, Helles, the landing troops—inexperienced at amphibious landings—were effectively slaughtered by the Ottoman defenders, most not even making it out of their landing craft. The Royal Dublin Fusiliers, for example, lost almost all their officers, including their commander, and suffered over 500 casualties.

In a second landing at Suvla in August, the forerunner of modern landing craft—the armoured 'Beetle'—was first used by the British.

Interwar period

Alhucemas Landing 8th September 1925. Performed by a Spanish-French coalition against rebel Kabilas in the north of Morocco, is a landing where tanks were used for the first time; air support and naval gunfire support were employed by landing forces. Spotting trained personnel with communication devices directed supporting air and naval firepower.

Floating depots were organized with medical, water, ammunition and food supplies, to be dispatched ashore when needed. The barges used in this landing were the survivors "K" boats from the Gallipolli fiasco. But in this case, the landings were performed against a prepared, defended in force positions. A successful opposed Amphibious Assault.

World War II

By the Second World War tactics and equipment had moved on. Purpose built landing craft were used at the evacuation from Dunkirk (Operation Dynamo) and an amphibious operation was tried out at Dieppe in 1942. The operation proved a failure but the lessons hard learned were used later.

Arguably the most famous amphibious assault was the Normandy landings on 6 June, 1944, in which British, Canadian, and US forces were landed at Utah, Omaha, Gold, Juno and Sword beaches. The organizational planning of the landing itself (Operation Neptune) was in the hands of Admiral Bertram Ramsay. It covered the landing of the troops and their re-supply.

Other large amphibious actions in the European Theatre in WWII include:

• North Africa
• Sicily
• Salerno
• Anzio
• Southern France

In the Pacific Theatre, almost every campaign involved "island hopping" assaults from the sea. Some of the famous ones are mentioned:

• Battle of Guadalcanal
• Battle of Tarawa
• Battle of Saipan
• Battle of the Philippines
• Battle of Iwo Jima
• Battle of Okinawa

Post-World War II

During the Korean War the U.S. Marine Corps landed at Inchon. Conceived of and commanded by US General Douglas MacArthur, this landing is considered by many military historians to have been a tactical jewel, one of the most brilliant amphibious maneuvers in history. The success of this battle eventually resulted in intervention by Chinese forces on behalf of North Korea.

The Royal Marines made first post-WWII amphibious assault during the Suez War of 1956 when they successfully landed at Suez on 6 November. In the Falklands War, the Royal Marines' 3 Commando Brigade, (augmented by the British Army's Parachute Regiment) landed at Port San Carlos on 21 May 1982.

During the Persian Gulf War, a large amphibious assault force, composed of US Marines and naval support, was positioned off the coast of Kuwait and Saudi Arabia. This force was composed of 40 amphibious assault ships, the largest such force to be assembled since the Battle of Inchon.^[1] The object was to fix the six Iraqi divisions deployed along the Kuwaiti coast. Due to early misadventure, the mission for this amphibious force turned into a feint. Nevertheless, the operation was extremely successful in keeping more than 41,000 Iraqi forces from repositioning to the main battlefield. As a result, the Marines maneuvered through the Iraq defense of southern Kuwait and outflanked the Iraqi coastal defense forces.

The most recent amphibious assault was carried out by the Royal Marines when they landed at the Al-Faw Peninsula on 20 March, 2003 during the Iraqi War.
