Bruggink, along with Lt. August Deibel and Officer Cadet Jan Scheffer, volunteered to join Capt. Jacob van Helsdingen on his mission using the last three working Buffalo aircraft on Andir airfield. The four pilots took off on March 7, 1942 and proceeded to Lembang to provide air support for ground troops fighting the Japanese in the city. Helsdingen's squadron travelled 200 kilometers when they encountered a Japanese aircraft, which Deibel attacked before it escaped. Some time later, three Japanese A6M Zeros appeared. Deibel fired at two of them which turned away, but was hit in the oil tank by the third Zero and had to break off from combat. His wingman, Jan Scheffer escorted him back to Andir airfield under a tropical rainstorm, where Deibel crashed landed his aircraft without suffering any injuries. Helsdingen and Bruggink remained above Lembang, but were now dogfighting six Zeroes. Helsdingen was soon shot down, but Bruggink managed to escape into the clouds before returning to Andir airfield. Dutch forces in Lembang surrendered the next day. All four Dutch pilots were awarded the Military William Order on July 14, 1948. Bruggink also received the Airman's Cross.
