Examples

“No sooner has the fleet settled onto this course than a small group of Japanese cruisers and actual, real, live, all-singing, all-dancing, all-features-included, protected-by-the-Emperor torpedo boats begin to move to cross the T of the Russian fleet. Worried about a torpedo attack on his lead battleships and determined to sweep this small formation aside, Rozhestvensky orders his main ships into a line abreast, a far-more-potent display of force that allows every forward-pointing gun on his capital ships to bear at the same time.”
