It is very interesting that in many key battles that stopped the Moslem/Turk invasions throughout history in Europe, it was literally a handful of brave Christian soldiers who stood their ground and prevailed.
Charles Martel; Vlad the Impaler; the Knights of Malta; etc.
A fascinating facet of western civilization history.
Please add in more names/battles, and dates that you know of (i.e. Hungary, Germany, Italy, Vienna, Venice, etc).
