in an effort to relieve union forces besieged in chattanooga, maj. gen. george h. thomas and maj. gen. ulysses s. grant initiated the \cracker line operation.\... as more and more union troops arrived, the confederates fell back to lookout mountain. the federals now had their window to the outside and could receive supplies, weapons, ammunition, and reinforcements via the cracker line.
in five days from my arrival in chattanooga... the troops were receiving full rations. it is hard for any one not an eye - witness to realize the relief this brought. the men were soon reclothed and also well fed, and abundance of ammunition was brought up, and a cheerfulness prevailed not before enjoyed in many weeks. neither officers nor men looked upon themselves any longer as doomed.
from ulysses s. grant, \personal memoirs, vol. 2,\ and from u.s. national park service, \wauhatchie: cwsac battle summaries\

Explanation:

The first text presents facts about the "Cracker Line Operation" (who initiated it, what happened as Union troops arrived) without personal feelings or interpretations. The second text includes subjective elements like "It is hard for any one not an eye - witness to realize the relief this brought" and descriptions of the troops' emotional state ("a cheerfulness prevailed"), which are more personal and less objective.

Answer:

The first text (the one starting with "In an effort to relieve Union forces besieged in Chattanooga...") has a more objective tone.
