Disbandment: In August 1921, a committee had been appointed by the British Cabinet to advise on the questions of finance and to decide how to reduce the national expenditure for the ensuing year. The Committee had made proposals for very drastic economies in the Army to be effected by disbanding many units. In view of the difficulty and near impossibility of maintaining regiments from the South of Ireland in the British Army, it was inevitable that these Irish regiments would disappear from the army list. On the 11th of March 1922, Army Order Number 78 was published, it was the order to disband the Irish regiments who recruited in the South of Ireland. On February the 8th 1922, the Depot of the  Regiment arrived at Bordon from Naas. They brought with them five officers and seventy two other ranks. In a Special India Army Order, it was announced that the four Irish battalions -  

The 2nd Battalion Royal Irish Regiment, the 1st Battalion Connaught Rangers, the 1st Battalion Leinster Regiment and 2nd Battalion Royal Dublin Fusiliers will proceed to the United Kingdom this trooping season - probably at the beginning of April - for disbandment. 

On the 6th of April 1922, the 2nd Dublins began their long journey home, some officers and men had left for home back in March. The strength at disbandment was eighteen officers, ten warrant officers, and 652 other ranks. Colonel Higginson and his men left the Port of Bombay on board the S.S. Assaye. They arrived in Southampton on April the 28th and were transported by train to Bordon Barracks where they met their comrades of the 1st Battalion who were already there. 

On Monday the 12th of June 1922, at a ceremony in St. George's Hall, Windsor Castle, the Colours of the Dublin Fusiliers were handed over to King George. They are still there to this day, someday they will come home to where they really belong, Dublin.
