Perhaps we are talking about two different things here.
Brian - I agree, a fortress below an enemy is nuts so in the true sense of "redan", no question you are correct. Also to me a Redan should be a blind landing - event the back of the green higher than the tee-box. (surprise, suprise, when you get there and what you thought was a great shot is over the green or in the bunker to the right rear)
A "golf hole Redan" is another thing I think - and here the term gets stretched a lot.
As far as I'm concerned, by comparison, a reversed Redan is a suckie hole (again by comparison to the more definitive, "proper" type).
My friend Gib loves the one at Creek - I like it also but it is really a very different play.
To me this is apples and oranges - both taste good but a different flavor - I like Billy V's analogy: blondes vs brunettes. I like blondes.
More on Redan:
Publishers love to cut stuff out of manuscripts (they're probably right in most cases ??), however, they cut out this sidebar that was to be in my "historical" Redan explanation
.... it takes the Redan back beyond Savastapol in the Crimean War to the 1600's (note last paragraph):
**
 History records that the Redan defense-fortification was first introduced during the Crimean War (1854-1856); a war waged by Britain, France, Sardinia, allied with Turkey against the forces of Russia on the north shore of the Black Sea - the Peninsula of Crimea. The war grew out of the growing distrust of Russia's designs on the Turkish Empire. In 1854 Florence Nightingale and her valiant band of nurses arrived at the war zone to assist the casualties suffered by the British in trench warfare during the first terrible winter of the conflict. It was her
dedication in caring for the wounded, and her pioneer work in sanitation and hygiene during this conflict, that established the modern stringent practices in the nursing profession.
Weeks later the famous 673 man British Light Brigade won undying fame for its valiant, though unsuccessful suicidal charge through North Valley during the battle of Balaklava, as they attempted to storm the Russian Redan fortification. This military action was honored by Britain's poet laureate, Alfred, Lord Tennyson in 1854 when he wrote of the Charge of the Light
Brigade.
The French troops captured the important redoubt of Malakov, in what would be the most important battle of the Crimean War. Within a few months, the Russians surrendered
Savastapol and the end of the conflict was at hand.
Although that particular Redan fortress at Crimea gets much acclaim, Redan design origins stem further back in history, to the late 1600's. It is believed to be initially designed by Sebastian le Prestre de Vauban, a soldier serving under King Louis XIV of France. Its early
configuration for military use was as a high, "V" shaped rampart with steep sloping sides that would repel cannon balls and discourage storming by foot-soldiers.
