The line is formed on Page 11 of Serpents in the Water. The Morantine pour broadside after broadside into the leviathan. You can see the leviathan’s response when you vote for Snow by Night on Top Web comics.
The line was a devastating formation for galleons and frigates of this era. It covers the weakness of the sailing ship — the fore and the aft, where they have few canons. By forming a line, the ships support each other and concentrate their fire on a single point. The effect was devastating.
I’m at Balticon this weekend! Hanging out with George R.R. Martin who is the Guest of Honor. And by hanging out, I mean I will be in the same hotel. General vicinity counts, right?
I won’t be posting a new page on Monday as it is Memorial Day. The next page update will be Wednesday June 1.
