from 1866, the term "royal horse artillery" appeared in army list hence the battery was designated b battery, d brigade, royal horse artillery from about this time. another reorganization on 14 april 1877 saw the number of brigades reduced to three (of 10 batteries each) and d brigade was broken up. its batteries were transferred to b and c brigades and redesignated again, hence the battery became g battery, b brigade. the number of brigades was further reduced to two (of 13 batteries each) in 1882 without effecting the designation of the battery. the battery took part in the anglo-egyptian war, notably the battle of tel el-kebir in september 1882.
