He died on 27 August 1914 in action at Oise, France (killed in action), and was buried on 28 August at Etreux British Cemetery, Aisne, France.  There is a memorial in Etreux, that marks the grave of 2nd Lt. Carol Edward Vere Awdry of 2nd Royal Munster Fusiliers where he is listed as the son of the Rev Vere Awdry and Mary Louisa Awdry (nee Man) of Box, Wiltshire, England.  

His father wrote this about his son's death: "We are inclined perhaps to ask why the splendid young fellow in the prime of life and with all his future - as we call it - before him, should be so suddenly cut off while older and possibly feebler ones are left. "The Lord hath need of him". That is the answer.  He needed him in particular for some good purpose of His own which we here cannot and shall not know in this world. Nothing is done by God be mere chance [...] We have at least the satisfaction and great comfort of knowing that our dear lad suffered no pain ... death has come, but a death to be proud of, not that probably others have not died equally brave and noble deaths - we know many have - but he was our boy, our own lad.  He has lived his whole life among us at Ampfield, and we can be proud of that Ampfield lad, who has proved himself trustworthy and faithful unto death".  (From "The Story of St Mark's Ampfield" pp. 38-39). 

On a personal note of this web editor (2010) who was educated at Marlborough House School. The school was organized around four 'houses' or 'teams': Awdry, Dunbar, Egan and Hawkins. So named after the first four boys killed in World War One. Thus Carol Awdry's name was memoralized by the school. The web editor was unaware of his family connection to Awdry (the team and the person) until 2009.
