ABSTRACT
British mobilization and deployment were smooth. The four infantry and one cavalry divisions deployed with 334 guns. This was only the divisional artillery; nobody wanted slow siege artillery, and there was no siege predicted to require The Siege Train. But intentions were one thing, and the war another. Within days of the first battles, the BEF requested artillery reinforcements. The first siege batteries soon embarked, and saw action in late September at the Battle of the Aisne.1
