Yet the conflict brought great personal tragedy to Garvin. At the start of the war his only son Roland Gerard Garvin (known to his family as "Ged") enlisted with the South Lancashire Regiment and was shipped to France. Though subsequently assigned a staff position, Ged transferred back to a combat posting soon after the start of the Somme campaign and was killed in a night assault on German line in late July. Heartbroken at the loss, Garvin never recovered from Ged's death, and it shaped many of his attitudes to subsequent events.
