On 30 August, two more MAG-23 squadrons, VMF-224 and VMSB-231, flew in to Henderson. The air reinforcements were more than welcome. Steady combat attrition, frequent damage in the air and on the ground, and scant repair facilities and parts kept the number of aircraft available a dwindling resource.

Plainly, General Vandegrift needed infantry reinforcements as much as he did additional aircraft. He brought the now-combined raider and parachute battalions, both under Edson’s command, and the 2d Battalion, 5th Marines, over to Guadalcanal from Tulagi. This gave the division commander a chance to order out larger reconnaissance patrols to probe for the Japanese. On 27 August, the 1st Battalion, 5th Marines, made a shore-to-shore landing near Kokumbona and marched back to the beachhead without any measurable results. If the Japanese were out there beyond the Matanikau--and they were--they watched the Marines and waited for a better opportunity to attack.

First Offensive: The Marine Campaign for Guadalcanal — Part 20

The United States Marine Corps entered World War II wearing essentially the same summer field uniform that it had worn during the “Banana Wars.” The Marines defending America’s Pacific outposts on Guam, Wake Island, and in the Philippines in the late months of 1941 wore a summer field uniform consisting of a khaki cotton shirt and trousers, leggings, and a M1917A1 steel helmet. Plans to change this uniform had been underway for at least one year prior to the opening of hostilities.

As had the Army, the Marine Corps had used a loose-fitting blue denim fatigue uniform for work details and some field exercises since the 1920s. This fatigue uniform was either a one-piece coverall or a two-piece bib overall and jacket, both with “USMC” metal buttons. In June 1940, it was replaced by a green cotton coverall. This uniform and the summer field uniform were replaced by what would become known as the utility uniform. Approved for general issue on the Marine Corps’ 166th birthday, 10 November 1941, this new uniform was made of sage-green (although “olive drab” was called for in the specifications) herringbone twill cotton, then a popular material for civilian work clothing. The two-piece uniform consisted of a coat (often referred to as a “jacket” by Marines) and trousers. In 1943, a cap made of the same material would be issued.
