among them future commanding officers LCol "Harry" Harrison and Major Cyrus Inches. In 1916 volunteers from the Regiment travelled overseas as 4th and 6th Canadian Siege Batteries, firing their first shots in anger during the Battle of the Somme. There they perfected new techniques of long range counter-battery bombardment. The Canadian Corps Heavy Artillery, including 4th and 6th Siege Batteries gathered together for the first time with the whole of the Canadian Corps in the spring of 1917. That April they fired what has gone down in history as one of the most successful counter-battery bombardments in history, neutralizing over 80 percent of the German artillery and paving the way for Canadian infantrymen to take Vimy Ridge. From Vimy, 4th and 6th Canadian Siege Batteries were joined in 1918 by 3rd Brigade, Canadian Garrison Artillery, made up mostly of New Brunswick and Maritime gunners trained in Saint John. The Regiment became the core of the Canadian Corps Heavy Artillery during the Great War. New Brunswick heavy gunners supported the Corps in the difficult fighting for the final 100 Days Campaign. Its batteries played an especially important role in the dramatic Canadian victory at the Canal du Nord and Cambrai in September 1918. At the end of the Great War, surviving veterans came home to what became known as 3rd (New Brunswick) Coast Brigade, Royal Canadian Artillery (The Loyal Company of Artillery). Many veterans stayed active in the interwar militia, keeping alive the Reserve long range artillery. The Second World War, 1939-1945 In 1939 3rd (New Brunswick) Coast Brigade, RCA, (The Loyal Company of Artillery) mobilized to prepare and man new heavy coastal gun batteries constructed around Saint John. The threat of German surface raiders and submarines was even greater in the Second World War than in the first, requiring much of the Regiment's attention. However, the requirements for trained artillerymen for overseas service led to the despatch of four batteries from the regiment. 89th Battery from Woodstock mustered as field artillery while 90th and 104th Batteries from Fredericton assembled as anti-tank units. All three were despatched to Italy, taking part in the Canadian victory at the Hitler Line that opened the liberation of Rome. 105th from Saint John also went overseas as an anti-tank unit, landing in Normandy and taking part in the climactic Battle of the Falaise Gap and The Battle of the Scheldt. 1945-Present The close of the
