On September 22, in company with four other machines, Ingalls flew all over Flanders, committing depredations on German hangars, and ammunition trains. Four bombs were dropped on the ammunition dump at Handezeame, blowing up a string of wagons loaded with shells. Flying over Wercken, bombs were landed on a hut filled with explosives, setting it on fire. Swinging around over the railway station at Thourout, where the Germans had an enormous supply dump, two more hits were made. On the way back, his fourth trip for the day, he bombed a horse transport, and he and his companions by bombs and machine-gun fire killed or wounded some twenty-five Germans and thirty-five horses.
With three other machines, Ingalls was, on September 24, flying over the lines at 16,000 feet elevation, when twelve Fokkers were seen approaching. Though outnumbered, the speedy Allied planes quickly broke up the German formation. The famous British Captain Brown, of Squadron No. 213, swung into and gunned a Fokker after a thrilling high bank, and the German fell to earth three miles below. Another Fokker had got on the tail of one of the Allied machines and by a well-aimed shot punctured its gasoline tanks. Ingalls came to the rescue, fighting off the enemy and in a few minutes shooting him down. The fourth plane was hard at it, too, succeeding in shooting down another Fokker, after following it down to within a few feet of the ground. Thus three Fokkers were accounted for in a few minutes.
On another occasion, Ingalls, single handed, attacked six biplanes, driving down one of them and eluding the five pursuers. The first of October he engaged in three successive raids in one day. His second point of attack was a large farm building at Cortemarck, used as a shelter for troops. More than 200 Germans were gathered there. Crashing through the roof, a bomb dropped by Ingalls exploded in their midst, dealing death and destruction.
I wish it were possible to recount all the daring deeds performed by our Navy and Marine Corps aviators, who with the British and on their own engaged in constant attacks on the German bases in Belgium, but Ingalls' exploits are enough to give an idea of the work performed by this Northern Bombing Group. And all this was "land duty," a task seldom assigned to navies.
