On the night of 12 April, 300 Parachute Squadron of 131 Parachute Engineer Regiment (Territorial Army) was attacked by guerrillas
whilst working with 24 Field Squadron on the construction of the Dhala Road at Al-Milah near the Yemen frontier. Squadron Sergeant Major (SSM) John Lonergan of 300 Squadron and Sergeant Atfield,
the pay sergeant of 24 Field Squadron, were both killed during the action and are buried at the Ma-Allah Cemetery,
now within the Republic of Yemen. Major Clive Samuel, the Regimental Medical Officer, was awarded the MBE for gallantry
after he risked his life to attend to those wounded and rescued two badly wounded men caught out in the open. He had been recommended for the award of the Military Cross.
The base of 131 Engineer Regiment's successor unit, 131 Commando Squadron Royal Engineers, is named Lonergan Lines in honour of SSM Lonergan,
believed to be the first Territorial Army soldier killed in action since the Second World War.
