I have found out that Private J Mcenaney Was killed on the 9th August at Caix by a German bomb when James was being treated, for a wound, in a cavalry field ambulance, sadly the bomb that was dropped by the Germans killed James and a few other men you can read about the article here https://davidgibbins.com/journal/2020/12/22/the-bombing-of-no-3-cavalry-field-ambulance-during-the-battle-of-amiens

The war diary of No. 3 Cavalry Field Ambulance records one man of the 18th Hussars being killed in the bombing of the Advanced Dressing Station in Caix that evening. He can be identified as 12151 Private James McEnaney, discussed below, whose remains were exhumed along with those of the other casualties of the bombing on 15 May 1920 and reburied in the same row in Caix British Cemetery, with the record of the reburial having been made on 11 June 1920. Moylan appears in a separate reburial record for Caix British Cemetery of 12 June 1920, among a list of men exhumed from various locations of which he is the only one from that place. The trench map reference given for the exhumation site, 62D W.26.b.1.1, is only a few yards from the location given at De Luce British Cemetery for McEnaney and the others - including the three officers killed by the shell - at 62D 2.26.a.9.2., so must refer to the same place. It seems most likely that his body had been brought with the others from the shell
