Troop and Casualty Numbers per Battle

[N Mühlgay]

Hello all, 

It's been awhile since I've last been here, however I've returned with a fairly pressing question. 

Is there a reliable resource where I would be able to locate numbers of combatants and casualties associated with individual battles of the Great War, particularly the battles of Verdun and the Somme?

Best regards
