On 29 June 1917, from F.E.2d (A6498), Lieutenant Waddington and his pilot Lieutenant Reginald Milburn Makepeace sent an Albatros D.V out of control over Houthem, Belgium. This was the observer's first aerial victory. He racked up his second on 6 July 1917, from F.E.2d (A6498) piloted by Second Lieutenant Malcolm McCall. They destroyed an Albatros D.V in flames over Comines. Lieutenant Waddington, as observer in F.E.2d (A6548), piloted by Harry George Ernest Luchford, sent two Albatros planes out of control on 17 and 21 July 1917, the first over Polygon Wood between Ypres and Zonnebeke, West Flanders, Belgium, and the second over Menen, West Flanders. There is some disagreement as to whether those last two victories were against D.III or D.V aircraft. Waddington scored a double victory on 27 July 1917 from F.E.2d (A1956), again with pilot Luchford. They took down two Albatros D.V planes north of Menen, destroying one in flames and sending the other out of control. His remaining victories were all with Lieutenant Makepeace as pilot. On 16 August 1917, with Makepeace piloting F.E.2d (A3), Waddington racked up his seventh win. They sent an Albatros D.V out of control over Zonnebeke.
