Battle of Palmyra The Battle of Palmyra ( 1 July 1941 ) was part of the Allied invasion of Syria during the Syria - Lebanon campaign in World War II . British mechanized cavalry and an Arab Legion desert patrol broke up a Vichy French mobile column northeast of the city of Palmyra . They captured four officers and 60 men , which provoked the surrender of the Vichy garrison at Palmyra . Background . In 1941 the Vichy French had substantial forces in the region and had allowed their air bases to be used as staging posts by the Germans to send aircraft to take part in the Anglo - Iraqi War . They had also allowed the Germans to use the railway system to send arms and ammunition to Iraq . On 8 June 1941 the Allies had launched two northerly attacks from Palestine and Trans - Jordan into Lebanon and Syria to prevent any further interference to Allied interests in the region . By late June Damascus had been taken and the Allied campaign commander , Henry Maitland Wilson was ready to launch two further thrusts , this time from western Iraq to complete the capture of Syria . An expanded Brigade group called " Habforce " had during the Anglo - Iraqi war advanced across the desert from Trans - Jordan to relieve the British garrison at RAF Habbaniya on the Euphrates River and had then assisted in the taking of Baghdad . This force was now pulled back to the remote part of Iraq near the Trans - Jordan and Syrian borders . It was tasked with advancing northwest to defeat the Vichy French garrison at Palmyra and secure the oil pipeline from Haditha in Iraq to Tripoli on the Lebanon coast . " Habforce " was well suited to the task in the desert because of the inclusion in its strength of the battalion - sized Arab Legion Mechanised Regiment , which was made up exclusively of desert - dwelling Bedouin soldiers . The Palmyra actions . " Habforce " split into three columns ( two to make flanking maneuvers on each side of Palmyra ) , each one was guided by a detachment from The Arab Legion ; they set off on 21 June . A skirmish with pillbox es on the pipeline a few miles east of Palmyra resulted in the element of surprise being lost . " Habforce " surrounded Palmyra , sending the Arab Legion troops out on wide - ranging desert patrols to protect " Habforce ' s " flanks and lines of communication . On 28 June they captured the French fort of Seba ' Biyar ( roughly 60 miles south - west of Palmyra ) , the small garrison surrendering without a shot being fired . The next day they occupied Sukhna , some 40 miles north - east of Palmyra , which was not occupied by French troops . On the morning of 1 July Sukhna was attacked by the Vichy 2nd Light Desert Company . The Arab Legion occupiers had been reinforced by a squadron from 4th Cavalry Brigade ' s Household Cavalry Regiment and after a sharp battle , the French retreated before an enthusiastic charge by Arab Legion troopers and ended up trapped in a box valley before surrendering . Whilst hardly the largest battle of the war , its effect was to cause the 3rd Light Desert Company which was garrisoning Palmyra , to lose heart and surrender on the night of 2 July . This freed " Habforce " to move 40 miles west along the pipeline to Homs and threaten the communications of the Vichy forces fighting the Australian 7th Division on the Lebanon coast .
