Did William Coggeshall Save Lincoln's Life?

[L Verge]

I vaguely recall reading about the grenade incident in one of the two recent (within the past 5-6 years) books on the trip east and the Baltimore plot. Right now, my mind is drawing a blank as to either title or author.

Mind just recovered - the two books are The Baltimore Plot by Michael Kline and The Hour of Peril by Daniel Stashower. I also exercised my Google muscles and found this about CW hand grenades, https://en.wikipedia.org/wiki/Ketchum_Grenade It appears that it was not very effective throughout the war and had to be thrown like a dart and land on its nose in order to detonate. Hopefully, this forum has some military weaponry scholars that can expand on their possible use as an assassination device.
