I can offer various notes I copied once in a word document from Internet or other sources, I don't remember exactly from were though.

Ground Forces Order of Battle, July 1942
Note : This OB gives the position of French forces after the fall of Diego Suarez to the British. It is reproduced directly from "La "guérilla" des troupes vichystes à Madasgar en 1942" which looks like a reliable article. However, one point is subject to caution : there were in fact two Régiments Mixtes Malgaches of three battalions rather than one of six battalions as shown below (this is obvioulsy a typo). I haven't yet been able to check which battalions in fact belonged to the 2e RMM.
- 2 platoons of reservists and volunteers at Nossi-Bé
- 2 companies of the Régiment Mixte Malgache (RMM - Mixed Madagascar Regiment) at Ambanja
- 1 battalion of the 1er RMM at Majunga
- 1 battalion of the 1er RMM at Tamatave
- 1 artillery section (65mm) at Tamatave
- 1 company of the 1er RMM at Brickaville
Center of the island
- 3 battalions of the 1er RMM at Tananarive
- 1 motorised reconnaissance detachment at Tananarive
- Emyrne coastal battery at Tananarive
- 1 artillery section (65mm mountain guns) at Tananarive
- 1 engineer company at Tananarive
- 1 company of the 1er RMM at Mevatanana
- 1 company of the BTM at Fianarantsoa
South of the island
- 1 company of the BTM at Fort dauphin
- 1 company of the BTM at Tuléar
There were a handful old Renault FT17 tanks (at least 1x FT17 BS)
Armée de l'Air Order of Battle, 5 May 1942
Groupe Aérien Mixte (Cne Leonetti)
Unit Aircraft Total Avail. Base Commander
Esc. 565 (17x Morane-Saulnier 406, 11 available). Based in Ivato-Tananarive, commander : Cne Baché
Esc. 555 (6x Potez 63.11, ? available). Based in Ivato-Tananariv, commander : Lt Le Bouedec
Note : A small detachment of MS 406 and Potez 63.11 was permanently stationed at Diégo Arrachart under Lt Rossigneux (its aircraft are included in the numbers above). In addition, there were some Potez 25TOE and Potez 29 used mainly in for casualty evacuation.
Therefore there were only 11 French fighters facing 83 British aircrafts and a whole fleet.
1) The main landings went in on landing craft around Courrier Bay and Ambararata Bay (across the peninsula from Diego Suarez) on 5 May 1942. These landings were unopposed.
2) Meanwhile, a diversionary "simulated" bombardment and landing took place to the east, and dummy paratroops were dropped. Carrier-based aircraft bombed Vichy shipping in the harbor.
3) By mid-morning the invaders had run into French defences. Advance was hampered by difficulty in finding a suitable beach for Bachaquero to land artillery (although tanks were already ashore). A frontal assault next morning against the French position defending Antsirane finally succeeded, and additional shelling by British warships convinced the local Vichy commander to hoist the white flag. Surrender documents signed on 7 May.
4) French defences consisted of few coastal batteries, trenches, two armed merchant cruisers, two sloops and five submarines operating in the area, 11 Morane 406 fighters, 6 Potez 63 reconnaissance aircrafts, 1500-3000 troops in the Diego Suarez area, about 8000 troops on the island as a whole (approx 75% native).
5) British losses in the Diego Suarez operations amounted to 105 KIA and 283 WIA. Vichy lost about 150 KIA and 500 WIA.
6) To quote the British official history: "Ironclad was the first large amphibious assault made by British forces since the attempt to storm the Dardanelles in the First World War."
7) Vichy French (predominantly native) troops in the area were quickly withdrawn to the south and a protracted campaign ensued at a low level of intensity.
Further units involved :
As 5th Division was required for the defence of India (and in fact had been en route there prior to the Madagascar diversion), 13th Brigade was withdrawn on 20 May and 17th Brigade on 10 June 1942. This left, however, only the northern end of the island occupied by the Allies and a state of hostilities still in effect.
British 29th Brigade remained behind and reinforcements arrived for further operations:
22nd East African Brigade Group: Arrived 8 June 1943; departed 23 January 1944. OB as of June 1942:
1/1st Kings African Rifles
5th (Kenya) Kings African Rifles
1/6th Kings African Rifles
56th (Uganda) Field Battery
9th Field Regiment (Royal Artillery)
South African 7th Motorized Brigade: Arrived 24 June 1942; departed 7 December 1942:
1st City Regiment
The Pretoria Regiment
Northern Rhodesia 27th Infantry Brigade: Arrived 8 August 1942; departed 29 June 1944. OB as of August 1942:
2nd Northern Rhodesia Regiment
3rd Northern Rhodesia Regiment
4th Northern Rhodesia Regiment
55th (Tanganyika) Light Battery
57th (East African) Field Battery
The 29th and 22nd Brigades conducted another amphibious landing at Majunga on 10 September 1942, with the latter taking the lead in advancing toward Tananarive and then Ambalavao before the island finally surrendered on 6 November 1942. British 29th Brigade, meanwhile, had departed Madagascar on 16 October.

Thus I think its worthwhile to state the French OOB just before the British invasion in May.
- 1er Régiment Mixte Malgaches
- 2e Régiment Mixte Malgaches (both regiments had 3 battalions, 1/3rd of the personnel was white, the rest Malagache or recruits from french Africa)
- Bataillon de Tirailleurs Malgaches
- 42 Bataillon de mitrailleurs d'infanterie coloniale
- 21 Regiment artillerie legére coloniale mixte malgache
- 23 Regiment artillerie legére coloniale mixte malgache
- 32 Regiment artillerie legére coloniale mixte malgache (each such regiment had thirty six 75mm guns and about a dozen 37mm and/or 25mm AT guns)
- 221 Regiment artillerie lourde coloniale mixte malgache
- 282 Regiment artillerie lourde coloniale mixte malgache (each such regiment was to have tvelve 105mm guns and tvelve 155mm guns, though Dyskant says its unprobable that the units on Madagascar had any 155 guns. He even expressess doubt if there were any 105mm guns at the time of the invasion, suggesting that they might have been evacuated earlier)
- Groupe autonome d'artillerie coloniale "Emyrne"
- Groupe autonome d'artillerie coloniale "Diego Suarez" (According to Dyskant, both such groups had eight 75mm guns, four 37mm guns and four 65mm guns).
- One Engineer company stationed at Tannanarive. Formal name of the unit uknown.
- 1 motorised reconnaissance detachment at Tananarive. Unit composition unknown (According to Dyskant, the unit likely had a communication and light recon role, with no real combat ability)
- Companie autonome de chars de combat - 21 vintage FT-17 tanks (armed with 37mm guns). Formal name of the armored unit is unknown, its also uncertain how many of them were fully operational.
TOE of a colonial battalion, such as those used by the Mixte Malgaches regiments:
- 20 officers, 850 enlisted men.
- Two 37mm guns. (Vintage WWI Puteaux)
- Two 81mm mortars
- Three 60mm mortars
- Eight W14 Hotchkiss machine guns.
- Twenty six LMGs, (Three types were uded on Madagascar: The W15 Chauchat, the 1924/1929 Chatellerault and the 1915 Lewis).
- 565 Escadrille de Chasse (had seventeen MS 406 C1 fighters)
- 555 Escadrille de Reconnaissance (had ten Potez 63-11 planes)
- Ensemble autonome d'Aerienne (five MS 406 C1 fighters, two Potez 63-11 planes, all at Diego Suarez)
- Some two dozens of old Potez 25 TOE and Caudron C4 planes at Tannanarive. Mostly used for training, unsure how many were operational.
An auxiliary cruiser "Bougainville" (Not to be mistaken for a colonial Aviso of the same name)
Two colonial Avisos: "D'Entrecasteaux" and "D'Iberville".
Four redoutable class submarines: "Monge", "Le Glorieux", "Le Héros", "Bévéziers".
Coastal Defence at Diego Suarez had four 305 mm guns, four 240mm guns, four 138mm guns, and some six-tvelve 75mm AA guns.
