The HAC Boston Association was established in March 1948 following the union of the ‘American Association’ with the ‘Boston (1938) Society’, with the object of ‘the maintenance and development of fraternal relations with the Ancient and Honorable Artillery Company of Massachusetts and other formations in the USA and Canada by the entertainment of such formations visiting London and generally to return hospitality’.
The Association maintains the link between the Honourable Artillery Company (HAC) and the Ancient and Honorable Artillery Company of Massachusetts (A&HAC) and organises, on behalf of the HAC, the Company’s official visits to Boston and assists with the A&HAC’s official visits to London, both of which occur on a ten-year cycle. The AHAC last visited London & Armoury House in 2013 when they held their Banquet at Mansion House and presented the Congressional Medal of Honor Society Flag to the Unknown Warrior at Westminster Abbey. The HAC's last official visit to Boston was in 2014. General Sir Richard Barrons headed the delegation of 60, plus Pikemen & Musketeers and the HAC Band & Corps of Drums and the then Commanding Officer Lt. Colonel Jim Doherty. In addition, the Association holds social functions - both at Armoury House and elsewhere - in furtherance of its purpose.
Membership of the Association is open to all Regimental and Non-Regimental Members, Active and Veteran, and currently stands in excess of one third of the membership of the Company. The Management of the Association is in the hands of a Committee consisting of a Vice President, an Honorary Secretary, an Honorary Treasurer and an Honorary Membership Secretary. The President of the HAC holds the post of President of the Association. Following the AGM held on the eve of Thanksgiving Day each year the Association holds an Eve of Thanksgiving Supper.
