Second Lieutenant William Arthur Hewitt, 9th Battalion, Royal Inniskilling Fusiliers died on 1st July 1916, aged 23, in an attack on the Schwaben Redoubt.
His colonel wrote,
'…Your little lad Willie led his platoon over our parapet, and the last I saw of him was his happy smile as I wished him luck. They got across to the German trenches, in front of which they came under an appalling machine-gun fire. Your lad was hit, and Sergt. Lally, who is now in hospital wounded, was with him when he passed over…It was a sad day for us, and I feel quite stunned and heartbroken. Your Willie was one of the nicest-minded boys I ever knew. My wife saw a letter he wrote to the widow of a man in his company, and she told me it was the most beautiful letter of sympathy she had ever read. No one but a spiritually-minded boy could have written such a letter…'
The adjutant wrote,
'…Willie led his platoon fearlessly over the top. One of his men told me he was wounded, but still carried on, but had to stop - from loss of blood…He was a grand boy, one of the finest characters I have seen. He acted as assistant-adjutant to me, and no more conscientious and better boy ever lived…'
