Rendova Island
From their crude base on the northern tip of Rendova Island, on a small spit of land known as Lumbari, PT boats conducted daring and dangerous nightly operations, both to disturb the heavy Japanese barge traffic that was resupplying the Japanese garrisons in New Georgia, and to patrol the Ferguson and Blackett Straits in order to sight and to give warning when the Japanese Tokyo Express warships came into the straits to supply Japanese forces in the New Georgia–Rendova area.
