After enduring relentless assaults for more than 24 hours, the 1st Marine Raider Battalion prepared for another night of fierce Japanese attacks. Outnumbered with 830 US Marines facing over 2,500 enemy soldiers, the situation appeared grim. At this critical juncture, Col. Merritt Edson addressed his men.

“You men have done a great job, and I have just one more thing to ask of you. Hold out just one more night,” he asked. “I know we’ve been without sleep a long time. But we expect another attack from them tonight and they may come through here. I have every reason to believe that we will have reliefs here for all of us in the morning.”

United in their steadfast support for their leader, the battalion readied themselves for another intense night of combat, ultimately triumphing over the Japanese. With exceptional bravery, the colonel guided and motivated his troops on the battlefield, securing the territory they valiantly defended and immortalizing their courageous stance as “Edson’s Ridge.”

Merritt “Red Mike” Edson embarked on a diverse military journey that began as a private in the Vermont National Guard and ended in his promotion to major general in the US Marine Corps. Born in Vermont in 1897, he initially enlisted in the First Infantry Regiment of the National Guard in 1916.

Following a hiatus, Edson resumed his academic pursuits at the University of Vermont and entered the Marine Corps Reserve in October 1917, where he received a commission as a second lieutenant. Despite being deployed to France with the 11th Marine Regiment, he did not engage in combat during the First World War.

After World War I, Merritt Edson held various positions, eventually becoming interested in flight training. He earned his wings in 1922 and was stationed at the Marine Naval Air Station on Guam, where he conducted surveys of islands, some of which were later named after him. However, due to physical limitations, he had to end his flying career and return to ground duties.

In 1928 and ’29, Edson led a Marine detachment in Nicaragua, facing combat for the first time and receiving the Navy Cross for his leadership under enemy fire. Throughout the 1930s, he continued to serve with distinction and was promoted to the rank of colonel as World War II approached.

Given command of the 1st Battalion, 5th Marine Regiment, Edson played a crucial role in training and transforming them into the 1st Marine Raider Battalion in early 1942. While leading his men through various early engagements of the war, it was on a specific ridge on Guadalcanal that he solidified his place in US Marine Corps history.

In August 1942, American troops landed on Guadalcanal and swiftly seized a Japanese airfield under construction, later named Henderson Field. This heightened the enemy’s resolve to recapture the site, setting the stage for a difficult and prolonged battle.

During the months-long engagement, Merritt Edson’s 1st Marine Raider Battalion played a key role. On the evening of September 12, they were ordered to move to a reserve position near Henderson Field, hoping for some rest. However, this break was abruptly interrupted by a sudden Japanese assault, thrusting the Marines back into a fight for survival.

As enemy forces overwhelmed their positions, Edson made the decision to tactically retreat, and he withdrew his men to a ridge line about 400 yards south. There, he rallied his troops and prepared them to mount a defense. It was on this ridge that Edson inspired his Marines to endure one more night, giving them with time to mentally and physically prepare for the challenges that lay ahead.

As anticipated, approximately 2,500 Japanese soldiers emerged from the jungle and launched a full-scale assault against the 830 Marines. The Japanese forces initially succeeded in overrunning some Marine positions, leaving their flanks perilously exposed. One officer later recounted, “The Japanese attack was almost constant, like a rain that subsides for a moment and then pours the harder… When one wave was mowed down – and I mean mowed down – another followed it into death.”

As parts of the 1st Marine Raider Battalion started to retreat, they encountered Merritt Edson, who always knew exactly what to say to motivate them to fortify their defenses around Hill 123. It’s said his men would follow him anywhere, with their only challenge being to keep pace with him.

Throughout the night of September 13, Edson could be found just 20 yards behind the front firing line, rallying his Marines and orchestrating their defense. Even when other Marines stayed low to the ground for safety, the courageous colonel exposed himself to intense fire, risking his own life to safeguard the battalion.

As dawn broke the following morning, Merritt Edson’s Marines remained in control of Hill 123, having successfully repelled the Japanese assault. While the world may know this location as “Bloody Ridge,” those who fought there will forever remember it as Edson’s Ridge, a testament to their commander’s unwavering determination to defend it at all costs.

In recognition of his valor and leadership amid constant enemy fire, Edson was awarded the Medal of Honor, having earned the admiration and respect of every man who witnessed his actions. Throughout the remainder of the Second World War, he continued to serve with distinction, eventually rising to the rank of brigadier general and receiving his first star. Retiring from the Marine Corps in 1947 as a major general, Edson continued to serve his nation in various civilian capacities.

In recognition of his exemplary service and bravery, not only did Merritt Edson receive personal awards for gallantry, but the USS Edson (DD-946), a Forrest Sherman-class destroyer, was commissioned in his honor. Furthermore, a section of Camp Pendleton, where Marine recruits hone their marksmanship skills, was dedicated in his name.
