Here is a incomplete list from a sketch map in Hastings 'Overlord' It shows the units present inside the pocket from when it was formed circa 16 August to 21 August when it collapsed.
Starting from Mourteaux on the Dives River and reading counter clockwise around the 16 Aug perimeter:
85th ID Division. Looks like it was crushed by the Brit 4th Armored Div & the survivors pushed NE.
12SS. Between Morteux & Falaise.
21 Pz
89 ID
271 ID
277 ID. West bank of the Orne
276 ID
326 ID. At the Conde corner.
353 ID
243 ID (part)
84 ID
275 ID (part)
10SS/9SS (part). Both west of Brouze on 16 August
708 ID
9PzD, 1SS, 2PzD. Clustered together SE of Ecouche
116 PzD, 9PzD ( part). Argentan
2SS. Between Argentan & St Leonard.
17SS (part). East of St Leonard. Looks like it was pushed east to the Seine by the US 90 ID & was east of the St lamber & Mont St Ormel 'Gateposts' Canadians & Poles established.
The map shows the 9SS, 10SS counter attacking from the Seine River area on the 18th or 19th August.
Closing the pocket on the Argenten-Falaise road leave the 85 ID, 12SS, 2SS, 17SS outside.
If the entire lot is bagged thats 50,000 men/22 Div = 2273 average for each division.
It cannot assumed all, or even half the escapes were 'cadre' material.
