Death of Gunner in Tunisian

Can anybody help with the cause of death of this man?
Gunner 1142915 Ralph Stanley Batham
172 Field Regiment, Royal Artillery
Died 18 August 1943. Aged 27
Buried Massicault War Cemetery, Tunisia Plot VI Row K Plot 7

I am aware of bombing and loading of landmine accident at the time and place.
8 men of 172 Field Regiment died that day and two more the next day.

Any help appreciated.

Casualty card, 'Killed Enemy Action' implies bombing.

other !72 Field Regiment R.A. Killed and wounded 18th August 1943

 

Thanks Guy
KIA certainly would imply enemy action.

The casaulty card states 'Killed Enemy action' rather than 'Killed in action'

 

Thanks Guy
Misread that!
