In the case of the Falklands War, the British Task Force was attempting to dislodge an uninvited invader. In order to do so, the Argentine sea and air forces had to be worn down to a point at which British amphibious forces could land on the islands, and then defeat the Argentine land forces in battle.
Ordinarily, amphibious operations would only be attempted once a number of criteria were achieved. Firstly, air and sea superiority would have to be achieved, in order for friendly air and naval craft to protect the landing ships during their most vulnerable phase. Secondly, western military philosophy in 1982 suggested that offensive operations such as amphibious landings should not be undertaken unless the attacked had at least a numerical superiority of 3:1 over the defender.
In May 1982, the British task force had largely forced the Argentine fleet back into port after the sinking of the Belgrano, thus solving one potential headache. And although the task force had given a good account of itself in dealing with air attack – the Sea Harriers in particular proving to be more than a match for Argentine fighters – the British had not worn down enough of the Argentine air inventory to claim air superiority. The Falklands were within range of fast jets flying from the Argentine mainland. In addition, the task force only possessed a reinforced Brigade, of three Royal Marine Commandos and two Parachute Battalions. The Argentines on the Falklands, meanwhile, numbered Divisional strength – albeit comprised mostly of conscripts – and had had time to dig in.
The task force, however, was under considerable pressure to effect a landing on the Falklands. Any operation aimed at re-taking the Islands would, ultimately, require an amphibious landing. If international opinion turned against Britain and forced a ceasefire, then the proverb ‘possesion is nine tenths of the law’ might come into play. Hence, the politicians in London wanted a landing as soon as possible. Although the main Battlegroup of the task force had steamed into the waters around the Falklands earlier in May, the landing force had taken some time to assemble – in particular, the landing ship HMS Intrepid had been brought out of mothballs in Portsmouth Dockyard, and was the last piece of the jigsaw. As soon as she arrived, the landing could take place. Sandy Woodward was also conscious of the oncoming southern winter, which would add to the wear and tear on the task force – there was a limit to how long the ships could stay at sea fighting, and getting the war over with as soon as possible was a priority.
San Carlos, an inlet on the west coast of East Falkland, had been reconnoitred by Special Forces for weeks prior to the landings. It was accessed via the northern entrance of Falkland sound. It was around 60 miles from the capital Port Stanley, and considered ideal for a landing. It had direct access from the South Atlantic, and was in a sheltered water. There were plenty of landing beaches, and hills on the outskirts for the landing forces to dig in to in the event of a counter-attack. And crucially, it was believed that the Argentines were expecting a landing near Port Stanley. Heavily influenced by the American, direct strategy of attack, the Argentine’s expected the Marines and Paras to land on the beach outside of Stanley and leg it up Stanley High Street. But Stanley was heavily defended, and was garrisoned by thousands of Argentines. San Carlos, by contrast, had very few. In a classic example of Liddel-Hart‘s indirect approach, San Carlos was chosen as it would allow the land forces to gain a foothold and build up, before striking east.
Interestingly, it was not thought possible for any amphibious landing to succeed at San Carlos – according to to British pre-war plans, the US armed forces or the Argentines. Yet necessity virtually forced the British planners to choose San Carlos by default, after all other possibilities had been discounted.
Given that the landings were likely to come under air attack, air-defence was a key consideration. Woodward detached the two Sea Wolf Type 22 Frigates Broadsword and Brilliant, the Sea Dart armed Type 42 Destroyer HMS Coventry, and a force of Frigates and Destroyers to provide naval gunfire support. The landings would be led by the Landing Ships HMS Fearless and HMS Intrepid, with their Landing Craft.
Intelligence suggested that there were very few Argentine troops in the area, which would give the British landing forces time to dig in and build up in preparation for an assault on Stanley. Despite this, there was naturally a sense of trepidation among the Marines and Paras preparing to land on D-Day. Would the Argentines subscribe to Rommel’s thoughts on amphibious landings, and attempt to throw the landings back into the sea in the first 24 hours?
