Dave Gallaher [SEP] Anglo-Boer War
In January 1901 Gallaher joined the Sixth New Zealand Contingent of Mounted Rifles for service in the Anglo-Boer War. When enlisting he gave his date of birth as 31October 1876, three years later than the actual date. It is unknown why he did this but the later date continued to be used in official records for the rest of his life. Gallaher was given a send-off dinner by his Ponsonby club before the contingent departed from Auckland on 31January. After disembarking in South Africa at East London on 14March 1901, Gallaher's contingent immediately embarked for Pretoria, and it was there that, as part of forces under the command of General Herbert Plumer, they set about their task of "rid[ding] the Northern Transvaal of Boer guerrillas and sympathizers." A member of the contingent's 16th (Auckland) Company, he served in the advanced guard, who scouted ahead of the main force.
