Victor and Alexander Agar-Robartes fought in the major battles of the war. Victor was wounded at the Somme, but both brothers thankfully survived.
The Agar-Robartes of Lanhydrock were an aristocratic family, who all contributed to the war effort. Of the five Agar-Robartes brothers, four fought in the trenches, from which the eldest brother did not return; a fifth brother made repeated requests to take leave for active service but was refused. Two of their sisters ran a war supplies depot and another became a nurse. Their parents carried out fundraising for wounded soldiers.
