 The 12-pounder deployed at very close range was a fearsome weapon, as was seen at the battles of Göhrde and Leipzig in 1813, as well as the crossing of the Adour River and the Battle of Toulouse in 1814.Accuracy at medium range remained a problem.This is illustrated by Mercer's description of G Troop Royal Horse Artillery during the retreat from Quatre Bras on 17 June 1815
