He was 20 years old, and a private in the 6th Battalion, The South Lancashire Regiment (The Prince of Wales's Volunteers), British Army during the First World War when the following deed took place for which he was awarded the VC.

On 25 February 1917 at Alqayat-al-Gaharbigah Bend, Mesopotamia, Private Readitt advanced five times along a water-course in the face of heavy machine-gun fire at very close range, being the sole survivor on each occasion.

These advances drove the enemy back and about 300 yards of the water-course was made good in an hour.

On reaching the enemy barricade he was forced to retire, but gave ground slowly continuing to throw bombs.

When support reached him he held a forward bend by bombing until the position was consolidated.
