No. 56 Squadron's first victory. Regaining an altitude of , he tried to dive underneath an Albatros two-seater and pop up under its belly as usual, but he overshot, and the German rear gunner put a burst of 15 bullets through the Nieuport's wings and spars. Ball coaxed the Nieuport home for repairs, returning to battle in an S.E.5. In his third combat of the day, he fired five rounds before his machine gun jammed. After landing to clear the gun, he took off once more, surprising five Albatros fighters and sending one down in flames. His fifth battle, shortly thereafter, appeared inconclusive, as the enemy plane managed to land safely. However, its observer had been mortally wounded. Three days later, on 26 April, Ball scored another double victory, flying S.E.5 no. A4850, and one more on 28 April. This last day's fighting left the S.E.5 so battered by enemy action that it was dismantled and sent away for repair. The following month, despite continual problems with jamming guns in the S.E.5s, Ball shot down seven Albatroses in five days, including two reconnaissance models on 1 May, a reconnaissance plane and an Albatros D.III fighter on 2 May; a D.III on 4 May, and two D.IIIs the next day, 5 May. The second of these victims nearly rammed Ball as they shot it out in a head-on firing pass. As they sped past one another, Ball was left temporarily blinded by oil spraying from the holed oil tank of his craft. Clearing the oil from his eyes, he flew his S.E.5 home with zero oil pressure in an engine on the brink of seizure. He was so overwrought that it was some time after landing before he could finish thanking God, then dictating his combat report. While squadron armourers and mechanics repaired the faulty machine-gun synchroniser on his most recent S.E.5 mount, A8898, Ball had been sporadically flying the Nieuport again, and was successful with it on 6 May, destroying one more Albatros D.III in an evening flight to raise his tally to 44. He had continued to undertake his habitual lone patrols, but had of late been fortunate to survive. The heavier battle damage that Ball's aircraft were now suffering bore witness to the improved team tactics being developed by his German opponents. Some time on 6 May, Ball had visited his friend Billy Bishop at the latter's aerodrome.
