Earlier on, I asked a question about General Grant's "true" force level at Fort Donelson. The argument was that Grant had been assisted by gunboats and gunners that were technically not under his command, but effectively raised his force levels.
Although the original (convoluted) question was closed and deleted, here is a simpler, more objective version focused on the relevant facts:
What were the number and caliber of the gunboat cannon that assisted Grant at Fort Donelson? How many men manned the ships and guns? (I believe I have a handle on the relevant land-based factors but not the naval ones.)
