The raid involved 656–725 men from the US 2nd Parachute Battalion, led by Lieutenant Colonel Victor  Krulak.
On October 27, at Vella Levalla, the attacking force embarked on eight LCM landing craft before being transferred to four high speed transports (APDs)—McKean, Crosby, Kilty, and Ward—that had just been released from supporting the landing of New Zealand troops on the Treasury Islands.
The exact number of Japanese troops on the island numbered between 3,000 and 7,000, and were under the command of Major General Minoru Sasaki.
The majority of these troops were based around Kakasa, and around Choiseul Bay where a small harbor was maintained for several barges.
Escorted by the destroyer USS Conway, the convoy carrying the US raiding party proceeded through the night towards Choiseul; en route it was attacked by a single Japanese aircraft, with near miss being scored on one of the APDs.
Just prior to midnight, the convoy reached the assembly area about 2,000 yards (1,800 m) offshore of the chosen landing site at Voza, on the north-west side of the island.
An advance reconnaissance party was sent ashore in rubber dinghies and then Companies F and G led the marines ashore and despite expecting resistance, landed unopposed early on October 28.
During the landing, the escorting destroyer, Conway, while standing off the landing beach was attacked by a Japanese aircraft with several bombs.
These bombs missed and the destroyer held its fire so that it would not draw attention to the landing operations.

After the beachhead was established, the landing craft began ferrying supplies and equipment ashore, and with the assistance of around 80 local porters organized by Seton who had landed with the marines, Krulak's battalion established a strong base on a plateau 1,000 yards (910 m) to the west of Voza, with radio communications, and early warning outposts established to the north and south.
 From there Krulak intended to carry out raids across a broad front to simulate a larger force, with actions eventually taking place around Sangigai and in the western part of the island as far as Nukiki and the Warrior River across an area spanning approximately 25 miles (40 km).
Shortly after arrival, as part of the deception plan, Krulak sent an uncoded radio message to IMAC that he had landed a force of 20,000 on the island was about to commence operations.
Within two hours the stores had been unloaded and the APDs and destroyer escort had departed the area for the return journey to Vella Levalla.
Four LCVP landing craft and their naval crews were detached at this time, detailed to support the marines to move up and down the coast.
Japanese aircraft attacked the landing beach shortly after the marines came ashore, and then again later in the day and in the evening, including an attack on Zinoa Island, where the marines had hid their landing craft.
These attacks proved ineffective as the marines had quickly dispersed their equipment.
Efforts were also made to disguise the beachhead, and a dummy site was constructed further north to divert Japanese attention.
 
Throughout the afternoon of October 28, Krulak sent a patrol to scout a base for PT boats along the western seacoast.
Meanwhile, Seton's local intelligence network also sent out patrols to identify the nearest Japanese defensive positions, determining that the main concentration was around Sangigai, with another smaller group 30 miles (48 km) northwest.
On October 29, reconnaissance patrols were sent to the north and south to gather information on Japanese dispositions, defenses and avenues of approach and to make field sketches of important locations; other patrols, with attached Army and Navy specialists, reconnoitered Moli Point and various other locations to determine their suitability as PT boat bases, or as locations for radar stations.
One of the patrols attacked and killed seven Japanese and sunk a barge during a patrol towards the Vagara River near Sangigai.
Later, a blocking force was sent to Vagara where it clashed with a platoon of Japanese.
In response, Krulak determined
