The landing plan encompassed four phases, on D-Day, three islets in the north of the atoll were to be seized. Two were to be used for artillery bases, Aistu and Rujioru—codenamed CAMELIA and CANNA. Bogen Island, or ZINNIA, lies north of the islet of Engebi (FRAGILE). ZINNIA was tasked to be seized by Katzenbach's 4th Division Scouts while Jones's company was ordered to recon and seize CAMELIA and CANNA. Katzenbach and his scouts fought the heavy surf and fierce 25-knot winds, which instead forced them to land on an island next to ZINNIA. By 0327 on D+1, the scout Marines crossed over to Bogen and declared it secured.
