In 1967, as many as 5,000 troops boarded the USNS General Nelson Walker. For 2 weeks they sailed to Vietnam for war. Since they were crammed so tightly in their quarters, most of the men wrote and doodled on the underside of the bunk above them. These bunks with graffiti were rescued from the ship before it was torn apart and are now being showcased at the Independence Seaport Museum at Penn’s Landing. This graffiti gives us insight as to the mindset and mentality of the soldiers while on their way to war.
