On the 1st January, 1918, he observed a new type twin-tailed two-seater enemy machine, which he attacked, firing a good many rounds at point blank range. The enemy machine dived, but was again attacked and went down vertically with his engine full on. The wings came off, and the machine was observed to crash. Later in the day Flt. Cdr. Compston observed two formations of ten and five Albatross scouts respectively. He attacked one of the enemy machines and sent it down in a flat spin and falling over sideways completely out of control.

On numerous other occasions Flt. Cdr. Compston has destroyed or driven down enemy machines completely out of control, and has frequently had more than one successful engagement in the same day.
