hi littlehand .
It seems you have mixed up Henry with William . The following is from " The Noble 24th " by Norman Holme.
Degacher . William . Captain.
Born 4/4/1841 , he was the 3rd son of Walter Henry Degacher of ST.OMER France . He was educated at the Imperial
college , St. Omer , and at Rugby . On the 31 / 5 / 59 he was Gazetted ( under the name of Hitchcock ) as an Ensign ,
2nd Bn 24th Regt , becoming a Lieutenant 19 / 8/ 62 . Promoted Capt 2 /12 /68 and also received his company on that date.
He served with his Batt at various home stations , in Mauritius and at the Mediterranean stations. In 1874 he took the name
Degacher . He served in Sth Africa , where he took part in the expedition to the Diamond FIelds , under Gen Sir Arthur Cunynghame in 1876 . On returning to Cape Town at the latter end of the year he proceeded home on leave . In March 77
he married Caroline , daughter of Gen . Webber - Smith CB. Shortly after arriving in England , Capt. Degacher formed an
intention to retire from the service . In consequence of the Kaffir war breaking out about this time , he volunteered for active
service , and again embarked for Sth Africa . October 78 he rejoined his Regt , which was then preparing for the forthcoming
invasion of ZULULAND . Taking part in the subsequent advance of the Headquarters Column , he commanded the 1st Btn 24th
Regt at the crossing of the Buffalo River and at the storming of Sirayo's stronghold in the Bashee Valley . His eldest brother . Lt
Col . Henry Degacher CB was at this time , in command of the 2nd Btn 24th Regt . Capt Degacher advanced with the column to
Isandlwana , and in the disastrous encounter with the enemy on 22 /1 /79 , was in command of the Battalion . Lt.Col H. Pulleine
being in command of the troops . No account of the manner of his death exists , it is , however , assumed that he fell shortly after
the three companies were driven in by the Zuls.
