With the exception of a two week period in April, when engaged at Wonsan Harbor, North Korea, Gerard Palmer's diary entries are very short and slight. Many dates are left entirely blank, either for fear of censorship, lack of time, or simply from never having developed the regular habit of keeping a diary. Although scant in detail, the diary provides some information useful in reconstructing the chronology of U.S. naval operations on the North Korean coast during the final months of the Korean War, and Palmer's pen drawings of naval life are as entertaining as they are roughly hewn.
Of particular interest among the illustrations is Palmer's pencil-sketch plan of Wonsan Harbor, labeled confidential. This drawing indicates the positions of North Korean gun emplacements and the American base of Yo Do, as well as notes on the areas of operation for U.S. ships, and it is accompanied by the densest description in the diary, documenting the activities of the Owen during a period of relatively heavy action. Palmer's sketch of South Korean Marines huddled on shore during a covert raid to gather intelligence is also worth noting, as are the humorous pair of sketches of an officers' club and serviceman's club in Singapore.
