No luck I'm afraid. His MC was gazetted as part of the New Year Honours 1917 when citations were not published. It will be noted that the list is headed simply "To be awarded the Military Cross" and contains something like 2000 MC awards which indicates that they probably relate to actions during the previous 6 months or so.
His battalion arrived in France in January 1916 and the war diary suggests that their major engagement was on 1/2 July during the Battle of Albert, part of the Battle of the Somme. In that period they lost 12 officers and 53 men killed or died from wounds, 10 and 286 wounded and 116 men missing. None of the other actions the battalion was involved in (he was on a course in England from mid-Oct to Jan 1917) suggest themselves as occasions when he may have had opportunity to distinguished himself. The Brigade diary records only the fact of the award on 1 Jan 1917 in a list of gallantry awards.
