[5] Coleridge served on the Abor expedition on the north east frontier of India in 1911-12 and was mentioned in despatches.

When his battalions were held up by heavy machine-gun fire he walked round his entire line and personally gave instructions to all units for reorganisation and pushing on to their objectives.

His splendid leadership enabled the brigade to take a deep objective, and was the principal factor in the success of an important operation.
