"During the action at Vlakfontein, on the 8th February, 1902, Surgeon-Captain Martin-Leake went up to a wounded man, and attended to him under a heavy fire from about 40 Boers at 100 yards range. He then went to the assistance of a wounded Officer, and, whilst trying to place him in a comfortable position, was shot three times, but would not give in till he rolled over thoroughly exhausted. All the eight men at this point were wounded, and while they were lying on the Veldt, Surgeon-Captain Martin-Leake refused water till every one else had been served."

"Lieutenant Arthur Martin Leake, Royal Army Medical Corps, who was awarded the Victoria Cross on 13th May, 1902, is granted a Clasp for conspicuous bravery in the present campaign: — For most conspicuous bravery and devotion to duty throughout the campaign, especially during the period 29th October to 8th November, 1914, near Zonnebeke, in rescuing, whilst exposed to constant fire, a large number of the wounded who were lying close to the enemy's trenches."
There were only three double Victoria Cross recipients. Interestingly, two of these were doctors, the other doctor being Noel Chavasse VC & Bar.
