The Battle of Al Faw began on 20 March 2003 and continued for four days, as part of the 2003 invasion of Iraq.

One of the initial objectives of the Coalition was to capture every GOPLAT (gas and oil platform) in the Al-Faw Peninsula before they could be sabotaged or destroyed by the Iraqi military. Doing so would also deny Iraq the ability to cause another ecological disaster, as it had done with the Kuwait oil fires and the Persian Gulf oil spill in 1991. By seizing the country's coast, the Coalition would also ensure a quicker takeover of Iraqi oil production.

The 3 Commando Brigade of the British Armed Forces would also capture Umm Qasr at the same time, so that Umm Qasr Port—the only deep water port in Iraq—could be used to bring in heavy military supplies once Khawr Abd Allah was cleared by the Mine Counter Measures Task Group. The 15th Marine Expeditionary Unit of the United States Marine Corps was placed under the command of the 3 Commando Brigade in order to provide the necessary force for capturing both targets.

Background The main objective for the coalition was to capture the Khawr Abd Allah waterway on the al-Faw peninsula, allowing relief vessels to deliver emergency aid and equipment. During the Gulf War, the Iraqis had mined the waterway and the northern Gulf. Coalition commanders suspected they would do the same again, so the coalition dispatched minesweepers to clear the areas of mines. The eastern side of the waterway was part of the al-Faw peninsula and Iraqi-occupied, the mine-sweepers were not heavily armed or armoured and would be vulnerable to the Iraqi defenses on both the bank and from the rest of the al-Faw peninsula, the waterway was shallow and its canals were dry so large warships could not provide an effective defence for the mine-sweepers. So it became necessary for the coalition commanders that the eastern bank of the Khawr Abd Allah waterway and the al-Faw peninsula had to be secured; additionally, the docks at Umm Qasr could only be used safely if the al-Faw peninsula was secured.Rossiter, Mike, Target Basra , Corgi, 2009 , p56-p57

Another important objective on the al-Faw peninsula was the Iraqi oil infrastructure, coalition analysis of the major Iraqi southern oilfields, the routes of the pipelines and locations of the pumping-stations revealed that they all culminated in the al-Faw peninsula where 90% of Iraq's oil was exported through the peninsula via two gas and oil platforms just a few miles off the al-faw coast.Rossiter, Mike, Target Basra , Corgi, 2009 , p59

Plan The plan for the assault and eventual capture of the al-Faw peninsula was that US Navy SEALs from SEAL Team 3 would make the initial assault on the MMS (monitoring and metering station) and the pipelines that allowed Iraq to export its oil from the southern fields to the Gulf, landing via 8 MH-53 helicopters. After 30 minutes, the Royal Marines would take over whilst the SEALs would depart. The main objective for 800 marines from 40 Commando as part of the brigades objective was to secure the MMS, B and C company and the MSG (Maneuver Support Group) would land by helicopters (that had previously taken in the SEALs), on the eastern bank of the Khawr Abd Allah waterway to secure it and then set up a defensive perimeter around the MMS. An hour later, A and D company would be flown in by Chinook and Sea King helicopters and the rest of 40 commando would then move out and capture the rest of the peninsula and the town of Al-Faw. 3 ships from the Royal Navy and 1 from the Royal Australian Navy were assigned to provide fire support, as well as an AC-130.Rossiter, Mike, Target Basra , Corgi, 2009 p61-62, p91, p100, p104, p.138, p139, p140, p14

800+ commandos of 42 Commando, would land via 37 RAF CH-47, Royal Navy Sea King and US Marine Corps CH-46 helicopters, and north of 40 commando to create a blocking force against Iraqi forces to the north, they would be led in by USMC Cobras, teams of US troops were attached to the Commandos to liaise with US air support. A B-52 bomber would drop 16 JDAM's on Iraqi positions 17 minutes before the SEAL insertion, a flight of A-10s and an AC-130 gunship would also be in support, predator drones provided surveillance. The Royal Marines BRF (Brigade Reconnaissance Force) would also deploy to support 42 commando, a few minutes after 40 commando landed, Royal Marine artillery and British Army self-propelled guns would fire on Iraqi artillery positions on the peninsulaRossiter, Mike, Target Basra , Corgi, 2009 , p93, p99, p103, p112, p113, p147, p151

According to coalition intelligence, The Iraqi 6th Armoured Division equipped with 100 T-55 tanks were stationed to defend the approaches to Basra and could be sent to intervene, some of its units were based on the peninsula itself and were just a few hours away from the coalition objectives, at least 150 aircraft were ready to launch support operations against them.Rossiter, Mike, Target Basra , Corgi, 2009 , p66, p92, p116, p.140

Assault 20 March Following days of bad weather, the assault on Al Faw was set for 2200 hours (local time) on 20 March 2003, US gunships and fighter-bombers attacked the known Iraqi positions on the peninsula in a short bombardment before the operation. The B-52 arrived on time and they released their bombs on various Iraqi bunkers, trenches and dugouts around the oil facilities on the al-Faw peninsula, 5 minutes later A-10s arrived to destroy any anti aircraft guns or missiles, however they couldn't see their targets due to the dust cloud created from the JDAMs, so they went into a holding pattern until it cleared. A and D company of SEALs and other special forces units would assault on the MSS and the pipelines was successful, after a brief firefight they killed 1 Iraqi soldier and captured 13 more.Rossiter, Mike, Target Basra , Corgi, 2009 , p149, p153,

At the same time B and C company would commence air and sea landings, securing the gas and oil platforms out at sea. Special Boat Team 22 inserted SEAL Teams 8 and 10 to capture the Mina Al Bakr Oil Terminal and Polish GROM commandos captured the Khor Al-Amaya Oil Terminal. 32 Iraqi prisoners were also captured. Explosive ordnance disposal were then landed on the platforms to search for and remove explosive booby traps and demolition charges. After the terminals had been cleared of Iraqi troops, explosives, and weapons, Port Security Units 311 and 313 arrived to take control of the facilities.

An AC-130 guided in the RAF Chinook helicopters carrying the Commando's from 40 Commando, the helicopter insertion was successful and the Commandos secured the MSS and the pipelines, whilst assaulting buildings at the MSS, the Commandos killed 2 Iraqi soldiers. Resistance was light: D company came under sporadic fire from an Iraqi Bunker, two 2000- and 500-pound bombs released from an F-18 as well as 40 mm and 105 mm shells from an AC-130 destroyed the bunker. The Iraqi POW's captured by the SEALs were given over to the commandos. The MSG moved out to the town of al-Faw to take control of its access points, on the way, they attacked two Iraqi-occupied trenches and a gatehouse. The firefight lasted for an hour, eventually securing the position. With the support of the AC-130, the MSG killed 8 Iraqi soldiers and captured 25. There were still a further 200 Iraqi soldiers in other trenches and they began calling in mortars on the MSS, AC-130 gunfire silenced the mortars and demoralised the Iraqis; B company was locked in a sporadic firefight with an Iraqi bunker, which they eventually cleared, whilst A company assaulted an Iraqi-occupied trench, bunker and mortar position with AC-130 support, killing the occupants. D company neutralized another Iraqi bunker with naval gunfire; without taking any casualties, 40 Commando took over 200 Iraqi prisoners.Rossiter, Mike, Target Basra , Corgi, 2009 , p149, p153-155, p160, p162-164, p166-167, p173-174

A second assault by 42 Commando followed at 2225 hours. The second assault was preceded by artillery and naval bombardment, the artillery fire came from three British and one US artillery batteries positioned on Bubiyan Island, the naval component from HMS Richmond, HMS Marlborough, HMS Chatham and HMAS Anzac. The Marines were preceded by USMC AH-1 Cobra helicopters gunships, and flown in by USMC helicopters to land just north of the town of Al Faw, destroying Iraqi artillery.

The insertion began badly with appalling visibility, worsened by fires and sand. The Headquarters of the Brigade Reconnaissance Force crashed in a US CH-46 Sea Knight as the assault formation turned over the Brigade assembly area, killing the seven Royal Marines, one Royal Navy operator and four US marine Corps aviators aboard.Mark Ormrod, Man Down, Random House, 2009, p.145 The cloud base dropped even further and the commander of the US Marine Air Wing decided to call off any further landings.Rossiter, Mike, Target Basra , Corgi, 2009 , p189 A new insertion was planned, using RAF Chinook and Puma helicopters, for dawn. The landings finally took place, six hours late and onto insecure landing zones, all the objectives were taken and secured. 42 Commando became the most forward unit in the al-Faw peninsula. They came under friendly fire from a USMC Cobra but no casualties occurred.
