He spent almost the entirety of the First World War again in a life-saving role as a Sergeant with the British Red Cross and wrote home how appalled he was by the horrific injuries sustained by so many young men. Towards the end of the war he was again mentioned in despatches, this time in his own right for selfless action above and beyond the call of duty.
His diaries of 1940 and 1941, when he was still Sandown's Chief Officer before absorption of the brigade into the National Fire Service, evidence that he was tireless in his work both as brigade chief, which by implication made him officer in charge of the newly recruited masses of the Sandown detachment of the Auxiliary Fire Service and training other groups such as the Women's Voluntary Service, the Street Fire party's and Fire Watchers in how to deal with incendiary bombs and organise patrols. Across that two year period his diaries evidence just a handful of days without a duty of some sort for which he was responsible.
On the Easter Monday 11 April 1955 he took up his regular position to watch a key league fixture between Sandown FC and De Havilland's at Fairway Park. Shortly before half-time he collapsed and passed away on the spot despite the efforts of many who rushed to his aid. At his funeral, massively attended, one speaker remarked; He was a great Christian character, quite unspoiled by success and was humble in the true sense of that word!
Rest in peace Chief Officer Brown.
