Born in Durban and educated at Dale College and Selborne College, he qualified as a Civil Engineer before WW1, he was awarded RAeC Certificate No 3912 on 14  November 1916.

Having claimed five enemy aircraft he was posted as an instructor but still managed to venture over the front and brought down his sixth and final victory on 30 August 1918.  In 1926, he was appointed Captain of the RAF's Team for the Schneider Trophy for the 1927 competition held in Venice.  The race was won by ? which secured the trophy for the RAF for the first time.  Following the success of the High Speed Flight, he then undertook a solo flight from England to South Africa.

In 1940 he was sent out to West Africa along with Group Captain H K Thorold, and between them they confirmed the suitability of the area as a base for the acceptance, assembly and dispatch of aircraft delivered from Britain to the Middle East.  He then continued on to the Sudan where he took command of No 203 Group consisting of RAF units in the Sudan fighting against the Italians.  After the campaign, he submitted a report to the Air Ministry suggesting that, based on this small action, future campaigns would be improved by :-

1.  The provision of more transport aircraft.      

2.  The need to develop the re-supply of ground troops by air dropping.

3.  The provision of long range fighters for escort duties.

4.  The provision of more Red Cross/Casualty evacuation aircraft.

5.  The increased use of dive bombers.

All of these points eventually proved to be vital for the success of subsequent operations.

Citation for the award of the Distinguished Service Order

Flt. Sub-Lieut, (now Flt. Lieut.) Leonard Horatio Slatter, R.N.A.S.

For conspicuous gallantry and skill on many occasions both as observer and pilot.  He has taken part in numerous night bombing raids, and on one occasion he ascended at night for the purpose of attacking hostile machines, notwithstanding the fact that he had only returned a few hours previously from a successful action with hostile aircraft in superior numbers.  On the 4th September, 1917, he attacked an enemy Torpedo Boat Destroyer with machine gun fire.”

(London Gazette – 17 November 1917)

Citation for the award of the Bar to the Distinguished Service Cross

Flt. Lieut.(Act. Flt. Cdr.) Leonard Horatio Slatter, D.S.C., R.N.A.S.

For distinguished service rendered during a bombing attack on Ostende Seaplane Station on the 26th March, 1918, when, in spite of intense anti-aircraft fire and the glare of numerous searchlights, he descended to 400 feet over his objective to drop bombs.  Flt. Cdr. Slatter is a leader of unqualified keenness and dash and possessed of exceptional courage and judgment.”

(London Gazette – 17 May 1918)
