Arthur "Mud" James Dingle (16 October 1891 – 22 August 1915) was a rugby union centre and wing, who won three caps for England, and played for County Durham, Hartlepool Rovers and Oxford University.

Dingle, who had been a member of the Oxford Officers Training Corps, was gazetted second lieutenant in the 6th Battalion, East Yorkshire Regiment, which took part in the Suvla Bay Landing of the Gallipoli Campaign on 6 August 1915.

On 21 August, the Battle of Scimitar Hill ensued, a disaster for Britain and her allies: Dingle was killed the following day, defending a trench that had earlier been captured.

[5][3] In front of 10,000 spectators at Queen's Club on 12 December, Cambridge were the clear favourites to win:[7] Oxford had lost 5 of the previous 13 games.

[10] The following season, on 6 November 1912, Oxford hosted the South African team touring the United Kingdom and France.

[5] The Times described his debut performance as 'strong in defence, but ... not altogether a success',[5] while The Aberdeen Journal described him as 'fair', amongst a backline that was 'lacking in finishing power', with Poulton, 'poor'.

[2][1] Early in the season, England played The South at Twickenham, winning 21–12, with outstanding performances from Dingle, as well as Johnson and Poulton.

[16] His selection for the Five Nations came up for the match against Scotland,[3] replacing Roberts on the left wing, who had had a poor game in the prior encounter against Ireland.

After Cherry Pillman's leg was broken in a tackle, England were playing with fourteen men, but they managed to hold on, thereby winning both the Triple Crown and the Calcutta Cup, as well as the Five Nations Championship.

[19] It was England's last international test on British soil before the First World War: 11 of the 30 players went on to be killed in it, including the Scotsman William Middleton Wallace,[20] who died the same day as Dingle.

Despite this, Edgar Mobbs, the captain of the Barbarians invitation side, organised a match against the Royal Army Medical Corps (RAMC) on 10 April 1915.

[31] Dingle was shot through the temple and killed at dawn on 22 August 1915, while defending a captured trench "against overwhelming odds".

[4] Of his England team-mates who played Scotland in the final Calcutta Cup match in 1914 before the start of the war, three had already died: Bungy Watson, Francis Oakeley, and Ronald Poulton.

[4] There is also a tournament played amongst some of the first schools to adopt rugby, the Veterrimi IV, the winning team being awarded the AJ Dingle Cup.
