They are dead; but they live in each Patriot's breast, And their names are engraven on honor's bright crest.

The couplet asserts a distinction between physical death and civic immortality. Longfellow frames patriotic sacrifice as a form of continued life: the fallen persist in the collective memory and moral conscience (“each Patriot’s breast”). The second line intensifies this by shifting from private remembrance to public commemoration—names “engraven” on an emblematic “crest” of honor—suggesting that a nation’s identity is partly constituted by how it records and venerates exemplary deeds. The rhetoric is elegiac and ceremonial, aiming to console grief while also exhorting readers to uphold the values for which the dead are remembered.
