 Walker resisted Kenney's proposals that the bombers conduct attacks from low level using bombs armed with instantaneous fuses.Kenney ordered Walker to try the fuses for a couple of months, so that data could be gained about their effectiveness; a few weeks later Kenney discovered that Walker had discontinued their use.In November, Kenney arranged for a demonstration attack on the SS "Pruth", a ship that had sunk off Port Moresby in 1924 and was often used for target practice.
