BRIDGE
U.S.S. YORKTOWN
SOMEWHERE IN THE SOUTH PACIFIC
6 June 1942, 0600 hours
The last three weeks have been relatively quiet, but the Japanese menace has strengthened its grip on most (but not all) of New Guinea. We still hold Port Moresby, but the enemy has Lunga and Tulagi.
Our forces surprised the enemy by destroying one of its precious engineer units in Buna, but we didn't hold the base for long. The Japanese counterattacked in force, chasing a brigade of Allied troops to Dobadura. A miniature "Dunkirk" operation followed: a combination of Fast Transport TFs and Allied submarines hustled to Dobadura and carried about half the brigade to safety. Interestingly, the enemy landed a FT TF at Dobadura at the same moment that our evacuation TF arrived, but for some reason the opposing task forces did not engage each other.
Unfortunately, not all the troops could be evacuated, and the remainder of our force was left on Dobadura, where it was again attacked by the Japanese. These troops had to retreat west, toward Port Moresby. Since then, they have spent the past two weeks marching across the mountains from Dobadura to Port Moresby. Most recent reports indicate that the troops now have Port Moresby in sight, so it appears that most of the brigade will survive the Battles of Buna and Dobadura.
In the meantime, there has been a fair amount of submarine activity on both sides, and land-based air from Rabaul has tagged a couple of our transports. Excerpts from AARs follow:
