Battle to get article by the French doctor (5)
I believe the answer is:
alamo
'battle' is the definition.
(famous mission and siege from the Texas revolution)
'article by the french doctor' is the wordplay.
'article' becomes 'a' (the indefinite article in English).
'by' is a charade indicator (letters next to each other).
'the french' becomes 'la' ('the' in French).
'doctor' becomes 'mo' (medical officer).
'a'+'la'+'mo'='ALAMO'
'to get' is the link.
(Other definitions for alamo that I've seen before include "1836 massacre at a San Antonio, Texas mission" , "Famous battle in Texas launched by the Mexican army" , "Texas fort, scene of famous siege by Mexican army" , "Scene of massacre in Texas" , "Fort in San Antonio, once famously besieged" .)
