Hill 70. Tasked with relieving the Royal Scots Fusiliers, two squadrons were dispatched. Delayed by a navigational error, and suffering from heat, the regiment arrived in some disorder. After this, they began work on constructing defences, while one squadron was detached to garrison Kasr-el-Nil; in early July they were sent on to Moascar. Later that month, the 12th were relieved at Dueidar and moved back to Heliopolis. While there, Lieutenant Colonel Harold McIntosh took command of the regiment following Royston's elevation to temporary commander of the 2nd Light Horse Brigade. On 27 July the regiment, without its machine-gun section which had been detached to the 2nd Light Horse Brigade, was sent to Gebel Habeita to relieve the 9th Light Horse Regiment. After undertaking the first part of the journey to Seraphum by train, they marched the rest of the way. In early August, Ottoman forces launched an attack in the Battle of Romani. During this fighting, the 12th Light Horse Regiment provided flank protection, carrying out patrols, and was not directly engaged except for its machine-gun section. In early September, the regiment moved to Bayoud where they were attached to a British column along with the 11th Light Horse Regiment, a regiment from the City of London Yeomanry, and an artillery battery. Under the command of Major General A.G. Dallas, they carried out a raid in the Maghara Hills on an Ottoman position away. Upon arrival, after discovering that the Ottoman force was greater than expected, Dallas decided to limit the operation to a demonstration rather than a full attack. Within this plan, the 12th was allocated the task of advancing on the right flank during the attack. They proceeded to advance across the open ground on their horses, before dismounting to ascend towards the high ground. As the Ottoman fire increased, the 12th provided covering fire with machine-guns and rifles while the 11th came forward using their bayonets to clear the defenders from the forward position. The light horsemen were then ordered to withdraw, instead of assaulting the main position. In early October, while at Mageibra, the regiment received orders that they were to be remounted on camels and be re-designated as the "2nd Australian Camel Regiment", but largely the regiment continued to refer to itself by its old designation. This was due to a plan to convert both the 11th and 12th Light Horse Regiments to cameleers; however,
