In my recent Brutii campaign, the British were getting out of hand. They were expanding and were on my doorstep, they had taken out what was left of Gaul, and all of Germainia. I didn't really want to build up armies and beat them back so I decided to plunder their lightly defended homeland. I took a young general that had just come of age. A 16 year old with 3 stars to start out with. I built up a fleet for him and sent him around collecting mercs. I stopped by sparta, crete, Carthage, and made several stops along the Gallic coast. When I finally arrived in Brittian, I had a full stack of mercs. I sacked Londinum and the other cities in the mainland. I exterminated them and destroyed every building that I could, trained one unit of whatever I could recruit their (Roman Cavalry or Early Legionary Cohorts ususaly) and then moved on. I had brought along a diplomat and I bribed the one general that was walking around. 4 stars but more importantly, he could hire me more mercs. So now I have a full stack and a half stack army. I put them on the boats and send them to pilliage Sambrovia and the surrounding settlements. I let all of them rebel. Some went back to British control, some didn't. But it didn't matter, all of their buildings had been leveled and the population was decimated. Their economy was in shambles and they could no longer support the many full stack armies that they had. They also had no ports to rebuild their once powerful navy. Their expansion stopped and I had accomplished my goal. I could now resume my military opperations without interuption in all areas of the world. All this thanks to my mercenary army.
