Provincial career.

International career.
Buchanan played in the first ever side, and scored the first try in international rugby, after a deemed failed attempt by George Ritchie. Scotland had pushed a scrum over the English try-line, and Buchanan had fallen on the ball.
This was converted by William Cross, which created the score (crucially because it was goals that counted, not tries). The English argued that the try should not stand, but it was awarded by the umpire Dr Hely Hutchinson Almond (also a Scot - judges were not neutral in those days, and there were also umpires)
Almond made a questionable justification of his decision:
According to one of the English players:
According to confirmed records, Buchanan was the first Scotland player born, in January, 1847, and was twenty four years and two months old when capped.

In fiction, Buchanan is a part of the larger Harry Potter universe, appearing in an excerpt written by J.K. Rowling for the Pottermore website. According to this, Angus Buchanan was born in a wizarding family, but was non-magical i.e a Squib. Also, he is supposed to have published a "path breaking" book called My Life as a Squib, which highlighted his struggles to survive in a community which disowned him and the way he found a home in the Muggle world.
