From the 'History of the Victoria Cross':
JOHN FREDERICK McCREA (Surgeon)
1st Regiment, Cape Mounted Yeomanry
On January 14, 1881, during the action against the Basutos at Tweefontein, near Thaba Tsen, Surgeon McCrea behaved with very great bravery and devotion to the wounded. The enemy had charged with great determination, forcing the Burghers to retire with a loss of sixteen killed and twenty-one wounded. Among th latter was a man named Aicramp, who had been shot and lay some considerable distance away, but McCrea went to his assistance under a heavy fire, and, with the help of Captain Buxton, of the Mafeteng Contingent, carried him to the shelter of an ant-heap, and then returned for a stretcher. While again crossing the open space he was severly wounded in the right breast by a bullet, but still continued in his duties with the Ambulance, and carried many wounded from the field. He paid little attention to his own injury, and was forced to dress it as well as he could later on, as no other medical officer was present. The Gazette stated that, had it not been for his exertions, the sufferings of the wounded would have been greatly aggravated and many more lives lost.
He died in Africa in the summer of 1894.'
He does not appear in the Medal Roll for 1877-8-9.
