Help needed in Identifying an Abbreviation in War Diary "Fm"

I am looking at a 2/5 Battalion Leicestershire Regt. War Diary entry for 1-7 March 1943 (Tunis Campaign) in which it refers to ......positions at Fm Montagne ....... a feature known as Fm Guessa ....

I have checked most of the abbreviation lists available, but can't seen to identify what "Fm" relates to & was hoping someone might be able to assist?

With thanks in advance, Dave

 

Owen many thanks for this, I hadn't realised such detailed maps were available, so will definitely be including them in my future research.

 

Good work Owen to find the location. Can I offer this as a slightly clearer map:-
Béja | UCT Libraries Digital Collections

Detail here:-


If you use the 'View as overlay' link on the following page you can switch between the map and a satellite view, the map is the same as Owen's but the satellite view useful:-
Tunisia, 1:50,000, Beja

This will help you locate the area on the full map:-

 

Thank you Tony, excellent quality maps

 

I was there in June.

 

Dave, 2/5 Battalion Leicestershire Regt. get a few mentions in the book The Plain Cook and the Great Showman (The First and Eighth Armies in North Africa) by Gregory Blaxland.
I found it quite easily and inexpensive s/h on line. It gives a good general overview of the campaign Kassrine, Thala, Hunt's Gap and Tamera are all mentioned.
