Сиди-Баррани
The WFF advanced along the coast from Mersa Matruh to Sidi Barrani, to re-capture Sollum on the Libyan–Egyptian frontier but as a deception it was rumoured that the WFF was about to retreat from Mersa Matruh. A supply column was sent to Unjeila (about half way to Sidi Barrani), with carrying rations for and the camels, arriving on 16 February; after three days a wheeled convoy followed. On 20 February, Lukin advanced towards Unjeila with orders to reach Sidi Barrani quickly, with the 1st and 3rd South African Infantry battalions, the Dorset Yeomanry, Bucks Hussars, 6th Royal Scots, most of the Notts Battery of the 1/1st Nottinghamshire RHA and a field ambulance. During the march, air reconnaissance discovered a Senussi encampment at Agagia, south-east of Sidi Barrani. The force arrived on 22 February and local Bedouin reported that Nuri and Jaafar were at Agagia. On 23 February, a contingent of guards was left at Unjeila and the rest marched to Shammas and next day moved on to Wadi Mehtila, north-east of Agagia. Lukin planned to rest the force on 25 February and then make a night advance, to attack the Senussi encampment at dawn.
