Who's grandson was imprisoned at Ft. McHenry by Abraham Lincoln, and why was he imprisoned?

Question

Think of the ultimate irony.

Answer 1

a prisoner of war, in Fort McHenry, was Francis
Key Howard, Esq., the grandson of the author of the "Star Spangled Banner

Answer 2

Francis Scott Key. The whole thing was an irony. Lincoln suspended Habeas Corpus, illegally as it can only be done by congress, and started rounding up anyone who disagreed with him. So, all those who don't like Bush had better watch out.
