From a strategic point of view, by defending Thermopylae, the Greeks were making the best possible use of their forces.[77] As long as they could prevent a further Persian advance into Greece, they had no need to seek a decisive battle and could, thus, remain on the defensive. ./cache/en-wikipedia-org-1279.html ./txt/en-wikipedia-org-1279.txt
