Following the withdrawal from Gallipoli, Monash returned to Egypt where the AIF underwent a period of reorganisation and expansion. This process resulted in the 4th Brigade being split and providing a cadre of experienced personnel to form the 12th Brigade. It was also reassigned to the 4th Division. After a period of training, Monash's brigade undertook defensive duties along the Suez Canal. On 25 April 1916, the first anniversary of the landing at Gallipoli, while at Tel-el-Kebir, Monash and his men solemnly observed Anzac Day. Monash distributed red ribbons to soldiers present at the first landing and blue ribbons to those who came later.
