The general wanted to hold every position on the ridge. He sent his troops up from the valley floor, securing one line at a time. By nightfall the whole ridge was his. But the enemy commander, who knew the general's weakness for overextension, struck at dawn at the highest line — the one the general valued least, the one farthest from supply, the position he'd taken last and would sacrifice first. The rest of the ridge held. The general retook the summit the following week, just as the enemy knew he would.
