The battalion took part in the 1st and 2nd Trans-Jordan raids of 21 March–2 April and 30 April–4 May. On the first occasion (the Battle of Hijla) the leading elements of the 2/19th struggled across the river by swimming and rafting during the night of 21/22 March while other battalions were driven back. Once a pontoon bridge had been completed and reinforcements arrived, the advance continued in the afternoon of 22 March with artillery support. But the next position could not be taken and the troops were pinned down until nightfall, the 2/19th suffering heavy casualties. A second night attack succeeded in extending the bridgehead. The battalion remained in reserve during the subsequent attack on Amman, and covered the retirement of the raiding force to the bridgehead.
