The Gazala line was a series of defensive boxes accommodating a brigade each, laid out across the desert behind minefields and wire, watched by regular patrols between the boxes. The Free French were in the south at the Bir Hakeim box, 21 km (13 mi) south of the 150th Infantry Brigade box, which was 10 kilometres (6 mi) south of the 69th Infantry Brigade box. The line was not evenly manned, with a greater number of troops covering the coast road, leaving the south less protected but deep minefields had been laid in front of the boxes. On the morning of 9 June, twenty Ju 88s and forty Ju 87 Stukas escorted by fifty Me 110 and 109 fighters, attacked Bir Hakeim. The Germans waited for the rest of the 15th Panzer Division to arrive as German artillery and aircraft bombarded the fort. Then a two-prong attack struck the perimeter. Italian infantry fought alongside Kampfgruppe Wolz, the German and native infantry of Sonderverband 288 (Special Commando 288) from the 90th Light Division, elements of the reconnaissance and infantry units of 15th and 21st Panzer Divisions and Kampfgruppe Kiehl a company of 11 tanks. The objective was Point 186, the top of a gentle rise in the ground which acted as a fire-control position for the garrison.
