It's all gone. They're all dead
. Only this one fortress remains against our impending doom. From here we can wage our war, stage guerilla attacks, or send a small, but elite strike team to hit where it hurts most. If we buy enough time, we might even be able to get our hands on that one thing that can save us, and maybe, just maybe we can win
. But if that fails, we can at least go down fighting
. That is, assuming we can fight back at all....

- During the last months of the Russian Civil War, Crimea was seen as this by the White command who were still planning some Back from the Brink.
- During World War II, the Germans had a massive stronghold called the Alpine Fortress, which was constructed in the mountainous areas of southern Germany. It was built with the idea that if Germany were overrun, top Nazi officials, their staffs, and a large number of crack troops could retreat there and, with a stockpile of supplies and some limited production facilities, continue to harass the Allies for many years to come. However, the Fortress was far from impregnable by the time it became needed and it was taken easily shortly before the Berlin occupation. Even so, reports of its staggering defensive strength were partially responsible for the Allies' broad front strategy to take the southern regions and the Fortress before moving onto Berlin, rather than the narrow charge advocated by General Patton.
- Switzerland has a massive fortification system called the National Redoubt. Put to use during World War II, the National Redoubt had a series of forts, cannon positions, and other fixed defenses throughout the Swiss Alps. The Swiss battle plan in case of invasion, which was no secret, was to fight a holding battle in the lowlands for as long as possible, and then pull back to the Redoubt. The fortifications also commanded Switzerland's many passes and tunnels connecting Germany, France, and Italy; any attempt at invasion would mean cutting off that vital traffic. After the war, the defenses were examined and found to have more and better cannons than both the Maginot and Siegfried Lines combined.
- For years after its defeat to the Chinese Communist Party in the Chinese Civil War in 1949, the Kuomingtang under Chiang Kai-Shek treated Taiwan as this, vowing to retake mainland China at some point. This played into its actions during the 1950's, notably refusing to give up Quemoy and Matsu Islands (only a mile or two from PRC-held territory) and eventually sparking the passage of the Formosa Resolution by the US Congress, as well as delaying implementation of infrastructure and economic reforms on the island until the 1960's (if they're only going to be there for a few years, investing was a waste of time). Cut to 60+ years later, the Republic of China still officially claims the mainland (plus all or parts of several of China's neighbors), though nobody (including the ROC government) takes them seriously.
- Winston Churchill invoked this in his speeches for Britain in the months following the fall of France in June 1940 and during the Battle of Britain, as at that point the United Kingdom was the only belligerent left in Europe against Nazi Germany. The Axis took over the rest of the Balkans (with some difficulty) in 1940 and into 1941, but it wasn't until June 1941 with Operation Barbarossa that another major European power (the Soviet Union) was brought into the fight.
