Ahhh... yeah, story time!
So it's the Battle of Waterloo 4v4 online in Napoleon TW. We're on the defensive as the Austrians, Prussians, and French charge towards us (very historically accurate and they had 2 French armies). On the ridge and on the defensive were some Spaniards, Brits, more French, and my Russians. In all with 4 players and just under 8k troops each there was about 30 000 troops on the field.
The whole battle was quite interesting with my self covering the left flank from multiple French cavalry charges and using my own cavalry to destroy a couple artillery pieces. But all in all it was mostly at a standstill with our artillery's superior range due to the ridge causing our opponents to keep their distance.
Suddenly, the entire enemy army sprints past own kill-zone horse-artillery included and begins to assault our positions with men attempting to flank us and were successful on the right. I was able to hold our left flank with some skirmishers and destroyed some cavalry units. The situation, however, was growing dire as the enemy had captured 2 of the 3 farms (in other words a fortified position at our doorstep) and destroyed the other.
At this point we all had to focus our artillery on the farms which allowed the enemies' Old Guard to advance and begin to crush our standard soldiers. This, combined with the successful outflank on the right turned the tables to their favour. The fighting continued until only one of my artillery units and one of their light cavalry units remained, about 20 men for me and 60 for them in total out of the 30 000 that we all started with.
I had my artillery target them as they charged. Things seemed to move in slow-motion as my gunners and their horses were both exhausted after the previous hour of fighting. My team mates are all criticizing me and my every move. As they moved ever closer I commanded my men to fire canister shot, which is essentially a cannon shotgun. As the cavalry begin their final charge my men just finish loading it and "BOOM!" Half the cavalry fall and the other half rout in the chaos.
Pretty epic, and lucky that the other guy was too stupid to attack my flank.
