Boyle served in the Second Boer War, and between the wars farmed and ranched at Crossfield, Alberta. He also served in the 15th Light Horse, a Militia unit in southern Alberta, where he served as a squadron commander. At the start of the First World War, Boyle held the rank of Major. He was attested to the Canadian Expeditionary Force on 25 September 1914 at Valcartier. The 10th's first commanding officer only held the position for a matter of days due to a personal dispute with Sir Sam Hughes, and Boyle was appointed commanding officer at Valcartier. He then traveled to the United Kingdom with the battalion later that year. Boyle was tall and has been described as "rough-and-tough". One of his first acts on arriving in England was to parade the 10th Battalion, throw his coat to the ground, and announce to his men that anyone who wanted to "punch the hell out of me" could take the opportunity without disciplinary repercussions. Reportedly, no one took him up on it. The 10th Battalion was assigned to the 2nd Infantry Brigade of the Canadian Division. After indoctrination tours of the trenches in France in early 1915, the division took over front line trenches in the Ypres Salient in April. The Germans launched a poison gas attack on 22 April, forcing the collapse of two French divisions. The 10th Battalion was in reserve, and along with the 16th Battalion were rushed to the point of the breakthrough and ordered to counter-attack Kitcheners' Wood. Boyle reportedly told his men "We have been aching for a fight, and now we are going to get it." The 10th Battalion was placed in front and Boyle advanced with his men over 400 yards of open ground. Massed German machine guns opened fire on the attacking Canadians and Major Ormond later noted "The colonel got five bullets from a machine-gun in his left groin - made a wonderful pattern of two and a half inches." While the counter-attack was successful, Lieutenant-Colonel Boyle was evacuated to hospital and died on 25 April 1915.
Legacy
An equestrian statue of R.L. Boyle, in his Boer War uniform, sits atop a Boer War memorial in Calgary's Central Memorial Park. He is also mentioned by name on a plaque at the entrance to Calgary City Hall. On the 100th Anniversary of the attack on Kitcheners' Wood, a delegation of The Calgary Highlanders visited his grave. His grandson, Mr. Russell Everett Boyle, and his wife, Melody were part of the delegation.
