When was the last US bayonet charge?

[Schmedlap]

From what I have heard this never happened, as written here. After all the shooting stopped, some guys went forward with fixed bayonets (only 1 in 4 UK weapons can fit a bayonet), and took the surrender of the bad guys.

Without even knowing any of the specifics, that was my hunch. If they were "pinned down" then how did they manage to even attempt the "charge" let alone not suffer significant casualties? And why not just return fire? Insurgents aren't notorious for accurate fire, but I think they could dump a few magazines in the direction of a charging Scotsman and manage to hit him at least once, especially given the large target that a highlander presents. My spidey sense was tingling when I read that one.
