WORLD WAR I IS OFTEN DEEMED TO HAVE BEEN 'A WAR OF ARTILLERY'. British heavy artillery played a vital part in destroying the German trenches and providing invaluable cover for advancing troops on the Western Front. This book details the huge guns of the Royal Garrison Artillery, including the 6-in. siege gun and howitzer, the 8-in. howitzer, the 12-in. railway and siege howitzer and the infamous 9.2-in breech-loading siege howitzer. Camouflage and enemy battery locations and transport are covered, as well as tactics used and how the guns were developed and manned.
