different between fortress vs breastwork

Early 14 c., from Old French forteresce, forteresse, forterece (“strong place, fortification”) [from 12th c.], variant of fortelesse, from Medieval Latin fortalitia, from Latin fortis (“strong”) (see fort) +? -itia, added to adjectives to form nouns of quality or condition. French -ess, from Latin -itia is also in words such as duress, largesse and riches.
