The events of July 2, 1863 have been discussed endlessly, from Michael Shaara's The Killer Angels to the film Gettysburg. Since reading the book and seeing the film many times, I can't help but wonder how large each of the opposing forces participating in the defense of Little Round Top truly were.
Wiki provides the number for Union forces on the left flank of the hill (358) from the 20th Maine and 83rd Pennsylvania-- to which we may assume there were heavy losses. But how many soldiers remained from General Law's 4th, 15th and 47th Alabama Regiments and Robertson's 4th and 5th Texas Regiments at the time of the charge down Little Round Top?
Naturally, exact figures will be difficult. Best estimates based on logical or factual evidence appreciated.
