This saw a change in the individual unit establishments, with the addition of organic transport assets, as well as an increase in the allocation of indirect and direct fire support weapons at commando level. Further support units were added at brigade level, including administration, transport, logistics and signals. On D-Day, the 1st Special Service Brigade was tasked with landing behind the 8th Infantry Brigade, capturing the port of Ouistreham and linking up with the 6th Airborne Division on the eastern flank of Sword, where they were holding the high ground near La Plein and the bridges over the River Orne and Caen Canal. No. 6 Commando, with Lovat's brigade headquarters, came ashore on Queen Red beach of the Sword landing area, near La Breche, at 8:40 am on 6 June 1944. No. 6 Commando led the brigade from the beach. Moving through a swamp that briefly slowed their progress, the commandos began to come up against the German defences that had not been destroyed by the naval bombardment. Where possible they attempted an indirect approach, penetrating the defences using infiltration tactics. However, as they advanced towards bridges that had been captured by the paratroopers earlier in the day, they assaulted four pillboxes as well as an artillery battery that had been firing on the landing beaches. In the end it took the commando three-and-a-half hours to advance the to the bridges, with the lead elements, mounted on bicycles, linking up with gliderborne troops from D Company, 2nd Battalion, Oxford and Buckinghamshire Light Infantry under Major John Howard. After effecting the link up, the commandos joined with paratroops from the 9th Battalion, The Parachute Regiment in an attack on the village of La Plein, before digging in to begin defending against possible counterattack. By the end of the day, No. 6 Commando had suffered three killed and 32 wounded. In the week that followed the brigade undertook defensive duties as the Germans attempted to apply pressure on the beachhead by infiltrating the defensive positions on the eastern flank. On 12 June, the airborne troops launched an attack on the village of Breville from where German artillery had been shelling them during the preceding week. Although successful, British casualties were high. Having been subjected to an intense artillery barrage, No. 6 Commando suffered 16 casualties. The barrage also wounded the brigade commander, Lord Lovat, to the extent that No. 6 Commando's commanding officer, Mills-Roberts, although wounded himself, was asked to take over from him.
