Retreating Between the Coast and Depression
After Tobruk fell, Eighth Army continued retreating into Egypt in June 1942. Claude Auchinleck directly replaced Neil Ritchie in command on June 25 and chose to avoid piecemeal encirclement at Mersa Matruh by moving to El Alamein. Opposing German and Italian forces under Erwin Rommel were also stretching their supply lines through rapid advance.
The Alamein line relied on the coastal road and railway, with the Mediterranean to the north and the Qattara Depression, difficult for military vehicles, to the south, limiting outflanking room. Positions were unfinished, however, and strongpoints varied in excavation and mine-laying.
Stopping the Axis Breakthrough in Early July
On July 1, Axis forces attacked the northern positions of the 1st South African Division and were repulsed. Farther south at Deir el Shein, the 18th Indian Brigade Group, newly arrived from Iraq, was overrun. Whether the line could hold remained uncertain; Auchinleck retained limited armor in the center to prevent loss of the important Ruweisat Ridge position.
On July 2, XIII Corps counterattacked northward from the southern flank, forcing Rommel to redistribute troops to protect his flank. British forces received close air support but lacked sufficient tanks to turn initial gains into decisive victory. Early-July attacks and counterattacks gradually created a more continuous front and checked the Axis eastward advance.
Repeated Fighting After Regaining the Initiative
The arrival of the 9th Australian Division supplied fresh offensive strength. On July 10, XXX Corps attacked Tel el Eisa on the northern flank, seized a salient and resisted subsequent counterattacks. This forced German troops north and allowed Auchinleck to try attacking the Axis center.
The Ruweisat Ridge attack beginning July 14 captured some positions, but armored counterattacks on July 15 recovered part of the gains. On July 21–22, Allied attacks continued in the center and south. The 6th New Zealand Brigade and Indian units suffered heavily, and the newly arrived 23rd Armoured Brigade lost many tanks. Whether armor and reinforcements could reach infantry after an initial penetration became a recurring problem.
Isolated Infantry on Ruin Ridge
During the night of July 26–27, the Australian 2/28th Infantry Battalion reached Ruin Ridge, but vehicles were blocked by mines and enfilading fire. Telephone lines could not be laid through, radios were damaged, and ammunition and armored support failed to arrive in time.
After dawn, the isolated troops were counterattacked. Battalion commander McCarter ended resistance, and many officers and men were captured. The Australian official history identified disconnected infantry and armored command and unclear responsibility for minefield lanes, rather than simply blaming tank crews.

The Front-Line Crisis Changed Rear-Area Defenses
While fighting at Alamein, British forces also prepared Delta defenses. Auchinleck reported positions west of Alexandria and flooding of extensive areas to its south; defenses extended from Wadi Natrun to the Delta's edge, with Mena and the Pyramids fortified against forces approaching Cairo from the desert.
Additional pontoon bridges crossed the Nile, existing bridges, railways and roads received stronger guards, and headquarters prepared to leave Cairo if necessary. Contemporary records cited in the Australian history also described retreating traffic blocking roads, burning documents and runs on Cairo banks, showing the front-line crisis affecting life behind it.
A Pause, Supplies and a War Still Continuing
After the final major offensive failed on July 27, Auchinleck turned to reorganizing the army and strengthening defense in depth. The U.S. Army chronology dates the decision to await reinforcements and remain defensive to July 30. Patrols and shelling continued into early August, so the end of the offensive did not mean all activity in Egypt had ceased.
Holding the western barrier temporarily protected Alexandria's naval base, Cairo's command center and Suez communications from an Axis ground breakthrough. Small American bomber forces attacked supply points including Tobruk. By late June, some B-17s had moved to Palestine while B-24s continued operating from Fayid in Egypt. Axis supplies first crossed the Mediterranean and then traveled along the North African coast, so port attacks increased pressure at the front. Sherman tanks and other equipment promised by the United States in June arrived only in September and cannot be credited retrospectively for July's result. Both sides needed replenishment, repairs and training; July shaped the next stage but did not expel German and Italian forces from Egypt.
