The 7th Division was now concentrated in the coastal sector. Berryman clashed with Brigadier Jack Stevens of the 21st Infantry Brigade over the siting of Berryman's artillery observation posts, which were forward of the infantry's front lines. Berryman wanted Stevens' positions advanced so as to obtain effective observation of the enemy's lines for Berryman's gunners. Stevens refused, hampering Berryman's efforts to support him in the Battle of Damour. Despite this, Berryman implemented an effective artillery plan. In the final stage of the battle, Berryman, without authority, ordered Lieutenant Colonel Denzil MacArthur-Onslow of the 2/6th Cavalry Regiment to pursue the retreating French forces, but was overruled by Savige and Allen. For his part in the campaign, Berryman received a third Mention in Despatches.
