Late in the afternoon of 26 September the 10th Cavalry Brigade was attacked by the Fourth Army's flank guard which held the country round Irbid in force.
Consisting of the Fourth Army's Amman garrison (less their rearguard captured at Amman), according to Archibald Wavell these troops had not been "heavily engaged," and Anthony Bruce argues that they were "still intact as a fighting force even though ...[they were]... in rapid retreat."

The 2nd Lancers attempted a mounted attack without reconnaissance and without knowing the size of the defending force; the charge failed suffering severe losses, before the artillery could get into position.
