During which international conflict did the united states want to contain communism after world war ii by stopping the movement into the 38th parallel?

the  seven  days  battles  were  a series of seven battles over seven  days from june 25 to july 1, 1862, near richmond, virginia,  during  the american civil war. the  seven  days ended with mcclellan's army in relative safety next to the james river, having suffered almost 16,000 casualtiesduring  the retreat.

i think the answer is: cuba wanted to be independent from spain, and the u.s. wanted to end spanish rule in the west.
