I love Mass Combat. I love the idea of big army fights, but abstracted down to manageable levels, rather than putting the RPG session on hold to play a miniatures wargame. I love this concept so much that I managed to work mass combat scenes into my last two campaigns (Necessary Evil and Deadlands Reloaded). Mass Combat rules were one of those things I really hoped would be in the 5e DMG, but was not present, unfortunately...so when I was staring at a scenario that could easily break out into mass combat (Episode 6 of Hoard of the Dragon Queen), and the DMG wasn't a huge amount of help in this case, I put my thinking cap on...and went back to what had worked so well in the past:
I dug out Savage Worlds.
No, I didn't suddenly convert the game over to Savage Worlds. I love Savage Worlds, and I'll get back to it soon enough, but there's more than a few things that it does that has, and can, help me in D&D5e.
Like Mass Combat.
Unfortunately, Wounds and Bennies and Knowledge (Battle) don't immediately get along with D&D. I was looking at a potentially uphill battle...until I remembered that Shane Hensley had applied those same rules to a system that didn't have a leadership-style tactical skill, and the system also had a hit point system.
And so I dug out Army of Darkness from Eden Studios, written by Shane Hensley and featuring an adapted Savage Worlds Mass Combat system...and I went to work with the two books in hand, as well as the D&D books, and kitbashed in the following system (which got a playthrough Saturday night, and went pretty well):
