The garrison soon starves. Having only ever played as the Union, I have never been on the receiving end of this tactic, but have used it many times when besieging coastal cities and forts.
Apparently, depots do generate a small amount of organic supplies, but I am assuming that in your case that the Union force in question is larger than one or two units. Anything larger would soon exhaust the depot's supplies.
If you are sure that the Union force is receiving supplies and is healthy, then it must be a bug.
I have tested this twice. Once with 1.06d and a naval blockade and once with 1.07 with a fort blockade. Both times there were 6 ot 7 Union units surrounded in Wilmington, no depot (I had already destroyed it) or supply wagons but supplies still increased each turn. I have sent a save to Pocus but I think he will be too busy to check for sometime.
