THE BULLDOG AND THE BLACK CAT — THE TWO TRACKS THAT DECIDED WAU
In the jungles of New Guinea, the war was not decided by highways or railways, but by narrow foot tracks carved through mountains and rain-soaked forest. Nowhere was this more true than in Morobe Province, where two routes — the Bulldog Track and the Black Cat Track — quietly determined the fate of Wau, Salamaua, and ultimately Lae.
The Black Cat Track ran from the Japanese-held coast at Salamaua inland through steep jungle toward Wau. It was the route the Japanese relied on to push their troops into the highlands. Their plan was simple: move inland, seize the airstrip at Wau, and collapse Australian air power in the Huon Gulf. But the terrain turned every kilometre into a battle. Steep ridges, disease, and fragile supply lines meant Japanese troops advanced slowly, often arriving exhausted, under-supplied, and vulnerable to Australian patrols and ambushes.
The Bulldog Track, running in the opposite direction, was the Australians’ lifeline. It linked Wau and Bulolo to Bulldog airstrip on the Lakekamu River side of the Owen Stanleys, allowing aircraft from Port Moresby to land and feed men and supplies into the mountains. Everything needed to defend Wau — ammunition, food, medical supplies, even radios — passed over this route, carried by Papua New Guinean carriers and, where possible, mules. Without the Bulldog Track, Wau would have fallen.
These two tracks formed a strategic contest. The Japanese advanced along the Black Cat Track, stretching their supply line further with every step. The Australians reinforced Wau along the Bulldog Track, slowly building strength at the end of their own fragile supply chain. One side was pushing uphill into jungle and ambushes; the other was flying men in, then pushing them forward over the mountains.
When the Japanese finally attacked Wau in early 1943, the outcome was decided not just on the airstrip, but along these tracks. The Bulldog Track allowed Australian reinforcements to arrive in time. The Black Cat Track, by contrast, left Japanese troops exhausted and isolated. Geography had chosen a side.
In the end, Salamaua was abandoned and Lae fell not because of a single great battle, but because the Japanese lost control of the routes that sustained their forces. The Bulldog and the Black Cat were never just tracks — they were the arteries of war, and whoever controlled them controlled the campaign.
