[1] One of four soldiers to earn the Victoria Cross at the Battle of Vimy Ridge, (the others were Thain Wendell MacDowell, Ellis Wellwood Sifton and William Johnstone Milne), Pattison was 41 years old, and a private in the 50th (Calgary) Battalion, Canadian Expeditionary Force, during the First World War when the following deed took place for which he was awarded the VC.

On 10 April 1917 at the Battle of Vimy Ridge, in the area of Hill 145 (the location of today's Memorial), when the advance of Canadian troops was held up by an enemy machine-gun that was inflicting severe casualties, Private Pattison, with utter disregard of his own safety, sprang forward and jumping from shell-hole to shell-hole, reached cover within thirty yards of the enemy gun.

From this point, in the face of heavy fire he hurled bombs killing and wounding some of the crew, and then rushed forward overcoming and bayoneting the surviving five gunners.

He is buried at La Chaudière Military Cemetery, France located 7 miles north of Arras (plot IV, row C, grave 14).

[3] A mountain in the Victoria Cross Ranges in Jasper National Park, Alberta is named in his honour.
