"Jimmy Cross humped his love for Martha up the hills and through the swamps...Lieutenant Cross remembered touching [her] left knee. A dark theater, he remembered,...when he touched her knee, she turned and looked at him in a sad, sober way that made him pull his hand back, but he would always remember” (O’Brien p. 3-4)
O'Brien's writing takes on more sentimentality in these sections and adds a great deal of emotional weight for the reader. This contrast in narrative style is necessary to give emphasis to the intangible things that the men carried.
One thing O'Brien does frequently in describing the items is to tell how much it weighs.
"The weapon weighed 7.5 pounds unloaded, 8.2 pounds with its full 20 round magazine…The riflemen carried anywhere from 12 to 20 magazines...adding on another 8.4 pounds at minimum, 14 pounds at maximum”(O’Brien p. 5-6).
This gives the reader a sense of the burden that the men are bearing in carrying these things. Much attention is given to the weight and pressure the soldiers feel from what they're carrying and from external forces, such as nature. "They carried the sky. The whole atmosphere...they carried gravity” (O’Brien p. 15). But the greatest weight the men feel comes from nothing they can physically carry, but rather their emotions: "Grief, terror, love, longing these were intangibles, but the intangibles had their own mass and specific gravity, they had tangible weight" (O’Brien p. 21).
These emotional burdens are the heaviest because they are intangibles and therefore cannot be disposed of. Physical burdens are no more than that; if necessary they can be discarded. Emotional burdens, on the other hand, must be endured. O'Brien, speaking of cowardice in particular, says, "In many respects this was the heaviest burden of all, for it could never be put down" (O’Brien p. 21). The soldiers know there is no easy way to rid themselves of their fears because of their abstract nature, but they dream escapist dreams of flying away in a plane and "falling higher and higher," (O’Brien p. 35) free of weight. Jerry Cross tries to rid himself of intangible burdens by disposing of tangible ones that, to him, represent intangible qualities. He does this by burning his letters from Martha. He knows, though, that this simple act cannot rid him of his memories. "He realized it was only a gesture...Besides, the letters were in his head" (O’Brien p. 119). His love for Martha is also represented by the small pebble, which she gave him, but the easily disposable pebble, which weighs merely an ounce, represents a much heavier emotional burden that he cannot rid himself of.
Cross attempts this to try to better himself as a soldier, but O'Brien leaves it up in the air as to whether he accomplishes this. We can infer, however, from earlier statements that he will never be completely freed from the love he carries. The soldiers in "The Things They Carried" carried many things with them on their march. All of the things they carried were a great burden, but none more so than their emotions. All of them carry great loads of memories, fears, and desires. These intangible objects are an essential part of them and therefore cannot be put down, but carried and endured. And as Jimmy Cross comes to realize, "It was very sad...the things men carried inside" (O’Brien p. 22).
