Operation Chronicle was the Allied invasion of Woodlark and Kiriwina Islands, in the South West Pacific, during World War II. The operation was a subordinate action that formed part of the wider Operation Cartwheel, the advance towards Rabaul. An early planning name for this operation was Operation Coronet. Preliminary actions commenced on 23–24 June 1943 when small reconnaissance parties were landed on both islands. The main operation was executed without opposition on 30 June 1943. Around 16,800 personnel took part, divided into two forces. The United States Army provided the majority of ground troops, which were supported by a United States Marine Corps defense battalion as well as U.S. and Australian aircraft and naval vessels.

The Landing at Nassau Bay was an amphibious landing by Allied forces at Nassau Bay during the New Guinea campaign of World War II that took place between 30 June and 6 July 1943. The operation was undertaken so that Allies could secure a beachhead to establish a supply point to shorten their supply lines for the proposed attack on Salamaua as part of the Salamaua–Lae campaign and resulted in a battalion-sized force of US infantry and supporting elements being landed largely unopposed on the south-eastern flank of the battle zone.
