Battle of Gazala . The " Gazala Line " was a series of occupied " boxes " each of brigade strength set out across the desert with minefields and wire watched by regular patrols between the boxes . The Free French were to the south at the Bir Hakeim box . The line was not equally staffed with a greater number of troops covering the coast leaving the south less protected . By late May Rommel was ready . Facing him on the Gazala defences were 1st South African Division , nearest the coast , 50th ( Northumbrian ) Infantry Division ( on their left ) and 1st Free French Brigade furthest left at Bir Hakeim . The British 1st and 7th Armoured Divisions waited behind the main line as a mobile counter - attacking force while 2nd South African Division formed a garrison at Tobruk and Indian 5th Infantry Division ( which had arrived in April to relieve Indian 4th Infantry Division ) were held in reserve . The " 150th Brigade " position at the start of the battle can be seen in the map ( right ) , it was during this battle that they were overrun and destroyed in The Cauldron by the Afrika Corps and never reformed . 27 May . German advance spotted by the 4th South African Armoured Car Regiment ] ] , at first light , at about 8 : 30 am on the morning of 27th they overran the 7th Armoured Division HQ . This scattered the 7th Motor Brigade . The " 7th Motor Brigade " , withdrew to the Retma Box , fifteen miles east of Bir Hakheim , while 4th Armoured Brigade , fought all day to stem the attackers . By the afternoon of the 27th , the German attack had shattered the " 7th Armoured Division " and they were in position to assault the 201st Guards Motor Brigade , in the Knightsbridge Box . The Germans now attacked the Box at Retma , which was garrisoned by the Rangers ( 9th KRRC ) , 2nd Rifle Brigade , C Bty 4th RHA , and a Rhodesian anti - tank unit . Accompanied by heavy artillery fire the Panzer s swarmed in , swiftly overrunning the 9th KRRC , with the rest of the garrison then moving back to east of Bir El Gubi . The Germans now pushed their Panzers on to the north , moving behind the Gazala Boxes , British resistance was now stiffened . To enable them to maintain their supply route round the south flank , the Germans cleared two paths through the minefield either side of the 150th Infantry Brigade Box and very heavy fighting took place in this area which was to become known as The Cauldron . " 150th Brigade " , with field and anti - tank artillery , held the Sidi Muftah box between the Trigh el Abd and Trigh Capuzzo , along which the enemy cut supply lines through the British minefields . The brigade kept the supply lines under artillery fire and , although it was unable to stop the flow of traffic , it made the route so ineffective that the enemy armoured divisions to the east of the minefields were reduced to a parlous state for petrol , ammunition and food . Their water ration was down to half a cup a man . Against this isolated brigade , the enemy committed parts of German 15th Panzer Division , 101 Motorised Division Trieste and German 90th Light Infantry Division s , supported finally by heavy bombing attacks . " Panzerarmee Afrika said in its daily battle report . " The encircled enemy , supported by numerous infantry tanks , again resisted most stubbornly " , " Each separate element within the fortress - like strengthened defences had to be fought for . The enemy suffered extraordinary heavy , bloody losses . Eventually the operation , which also caused considerable losses to our troops , ended in complete success " "
