The British 3rd Commando Brigade “yomped” across East Falkland Island and successfully assaulted and occupied the five hill masses that surrounded Port Stanley to the west. The 3rd Battalion of the Parachute Regiment (3 Para) seized Mt Langdon with some difficulty, but was fixed by accurate Argentine artillery fire and could not continue on to seize its eastern most spur, Wireless Ridge, whose occupation would render Argentine defenses on Mt Tumbledown untenable, and isolate Port Stanley from the north. The task to seize Wireless Ridge was given to 2 Para, who was fifteen kilometers away on the slopes of Mt Kent as the brigade reserve.
On the evening of 13 June 1982, 2 Para yomped the 15 km to its assault positions north of Wireless Ridge. 2 Para’s new commander, Lt-Col David Chaudler who was flown in from Britain (!) and replaced the former commander killed at Goose Green, vowed that the battalion would not attack without adequate fire support again. So in support, 2 Para was allocated a generous allotment: two batteries of 105mm tube artillery, 3 Para’s mortars, two Scimitar tanks (skinny), two Scorpion light tanks (stubby… you know what I am talking about… The cards, man, the cards) from the Blues and Royals, and the 4.5 in deck gun of HMS Ambuscade (One of my favorite words. We need to get the term “ambuscade” into doctrine).
Just after midnight, 2 Para assaulted on line after a diversionary attack on Mt Tumbledown by the Scots Guards, and a short but vicious preparatory bombardment on the dug in Argentine positions. D Co would actually assault Wireless Ridge, while other companies seized the small hillocks to the north. The assault on Wireless Ridge was tactically polar opposite from Goose Green. Argentine resistance was systematically rooted out by superior firepower, by the light tanks, artillery, mortars and machine guns, upon contact. The Argentinian soldiers of the 7th Infantry Regiment usually broke before they were engaged in close combat with 2 Para infantry. There were four exceptions.
The first was not by 7th Inf Regt soldiers, but by a platoons worth of troopers from the Argentinian 2nd Airborne Regiment on their way to Mt Longdon, who counterattacked west directly into D Co as it assaulted east. D Cofought them off over the next several hours. The second exception was a dismounted counterattack by the crews of aa armored car squadron (read “troop” or “company”), which was annihilated by heavy machine guns and the Scorpions and Scimitars. The third attack by the Argentinians was by a bypassed 7th Infantry Regiment platoon who struck the flank platoon of D Co which was led by a brand new lieutenant fresh from school. The Argentinian platoon leader was furious after hearing his friend was killed, and rallied his men to counterattack. They nearly overran their adversaries, but were brought under intense and accurate fire support by the British platoon commander, who had to drop down to the fire support net in the confusion and coordinate his own support. D Co (the main effort) didn’t have a forward observation officer (?), and the other FOO’s were prioritizing their missions. The young platoon commander just asserted himself into the net, and probably saved D Co a very bad morning.
The fourth and final Argentine counterattack came as the sun came up. 200 Wireless Ridge survivors and staff officers were rallied by the 10th Brigade operations officer and formed a hasty defense on the west side of Port Stanley. Since about 4 am, the remaining Argentine artillery fired on Wireless Ridge. As dawn broke about six, 50 members of the ad hoc defense, led by the 7th Inf Regt executive officer and regimental chaplain, assaulted the ridge with fixed bayonets under cover of the bombardment. The Paras were initially flabbergasted at the lines of Argentinian infantry singing as they advanced, but they were eventually beaten back with great losses.
The failure of the impromptu Argentinian dawn assault broke the Argentine defenses and the Argentinian infantry to the south and west on Mt Tumbledown routed and fled back to Port Stanley. That evening the Argentinian commander in the Falkland Islands, with no further help from the mainland, recognized the futility of the situation and surrendered. The British reoccupied the South Sandwich Islands, the last Argentinian conquest in the South Atlantic on 20 June, and both sides declared an end to the hostilities.
