The Youtuber Brandon F has a 4 part series talking about why they fought like this. Spoiler- it wasn’t because they were stupid.
TLDR- if you split up you just get run down by enemy cavalry.
TLDR- a close formation lets you concentrate your firepower at one point.
TLDR- a close formation makes communication and controlling the army much much easier (or even possible at all).
TLDR- the formation makes the troops less likely to run away.
Wait your signature is supposed to just be your name in cursive? But then wouldn’t that defeat the point? I thought in the olden days it was supposed to be like a proof that you were the right person since you knew how your signature was written.
Anyways, for my signature I just kinda designed it. It was ages ago so I forgot my process, but it was deliberate and I remember making a whole bunch of sketches before finding one I liked. And since then I’ve incrementally improved it.
