 On the map, Wareo was roughly away from Sattelberg, however, due to the nature of the terrain, the actual distance to be travelled was estimated at being four times that.For the advancing Australian infantrymen, the burden was made even greater by heavy rain which turned the tracks over which they were advancing into a muddy morass that could not be traversed by motor transport.This, coupled with the unavailability of New Guineans to serve as bearers, meant that the Australians had to carry almost all of their own supplies on their backs.
