"In November 1943, Vandegrift commanded the 1st Marine Amphibious Corps in Bougainville, another battle in the Solomon Islands. When he returned in January 1944, he became the 18th Marine commandant. During that time, he rose to the rank of four-star general, making him the first four-star general to be commandant while still on active duty. Vandegrift retired in 1948 after serving in the Marine Corps for nearly 40 years. In his retirement, he co-authored a book about his experiences during World War II. Vandegrift died on May 8, 1973, in Bethesda, Maryland, after a long illness. He was buried in Arlington National Cemetery. The general's service to our nation continues to be honored. In 1982, the Navy frigate USS Vandegrift was named after him. The main street running through Camp Pendleton, California, also bears his name."
