He relinquished this to go through a course of training at the Quetta Cadet College.
He passed out in five months, and received a Commission as second lieutenant in the Indian Army and then sent to German East Africa in December 1916. He was in the thick of the fighting and hardships the troops had to endure in the trying climate.
Henry was reported missing in action on August 3rd, 1917 and his death was confirmed on August 12th. Reports at the time confirmed that he was involved in a surprise attack by the Germans in overwhelming numbers and his men were forced to retire. Henry was seen to be wounded in the attack, but carried on fighting with his revolver. When he saw the position was hopeless he ordered his men to retire and send out for him as soon as possible. He was last seen fighting gallantly, though surrounded by the enemy. When the Germans had retired and the ambulance was sent out his grave was found near the spot he was last seen in the battle.
An impressive memorial service was held in Cantref Church the following month. The entry in the De Ruvigny’s Roll of Honour states that a brother officer wrote of him:
‘His brother officers all deeply regret the loss of a gallant comrade, who was highly respected and loved by officers and men. By his coolness and pluck under fire he set a splendid example to his men and at all times was a perfect example of a brave and fearless leader. His absence is felt very much by everyone, as he was most capable in the field, and at
all times displayed the spirit of a true gentleman.’³⁹
