Flt Lt Langham embarked for North Africa as the Ground Defence Officer of No. 322 Fighter Wing on 29 October 1942, and as such he coordinated the LAA defence of Bône (Algeria), which was continually under enemy air attack. On 20 February 1943 he took command of the newly formed No. 4337 Anti-Aircraft Flight, with this unit Langham was at the forefront of the final actions leading to the ultimate capitulation of German forces in North Africa.
This officer has commanded his flight during operations in North Africa. On 11 May 43, while moving up to occupy landing grounds in the Cap Bon peninsular (East of Tunis) the flight was subjected to an enemy attack using mortars and machines guns. Flt Lt Langham launched a counter attack on the enemy which was successful and resulted in the capture of 200 prisoners. The enemy strong point was protecting their combined HQ and supply dump. This officer set up his own HQ in the locality securing much valuable equipment. From this HQ he then led a number of patrols in to the hills where the enemy had retreated. Though disorganised, they were still able to offer strong resistance. His patrols eventually cleared the high ground and captured about 900 prisoners. Flt Lt Langham has set a fine example of courage to all in his flight.London Gazette 21 September 1943
