Over the night of 2/3 April 1946, there were several attacks on railway installations around the country. One at Yibna occurred at the same time as a patrol from the 9th Parachute Battalion was entering the village. The patrol's leading two vehicles exploded mines that had been laid on a bridge, wounding three men. At daylight the tracks of around 30 men were found, and a section from the 8th Parachute Battalion eventually cornered 24 armed men. In the firefight that followed, 14 of them were wounded and the remainder surrendered, with no British casualties. On 29 June Operation Agatha started; the brigade had been rotated to cover the south of Palestine, and were to search for arms and arrest any members of the Palmach in Givat Brenner and No'ar Oved. On 22 July the King David Hotel in Jerusalem was bombed, which was the catalyst for Operation Shark, the searching of every house and property in Tel Aviv. For this operation the brigade had all the divisional artillery and the 3rd The King's Own Hussars under their command. The brigade's next tasks were Operations Bream and Eel between 28 August and 4 September, which entailed the search of Dorot and Ruhama in the Negev. For the first time army dogs trained in metal detecting were used during the operations, and they located a large arms cache in both settlements.
