Tennyson was given a role of a poet laureate , in his position he was duty bound to glorify war to the British public to defend the position of the aristocracy
Britain and France got involved to prevent Russian expansion . This was unpopular with the British public who saw it as unnecessary. The light brigade were often members of the lower class who were lightly armoured and on horseback
media res- the unprepared listener is thrust into action with the repetition of "Half a league" . This establishes a tense atmosphere from the onset which causes the listener to view the poem through the lens of threat and risk.
This poem takes on the form of a ballad which is a historic poetry form used to commemorate a story for future generations to hear. The ballad poem acts to memorialise the people who were killed and demonstrates that what soldiers did was inspiring.
Tennyson's use of metaphors to create negative connotations for the listener : "Jaws of death". "Jaws" has claustrophobic connotations which imply that the solider's will be eaten up by or shredded by bullets.
" Valley of death " - biblical allusion from psalm 23 which refers to the protection provided by God so is highly ironic when used in this context
