Yeah, I was indeed distinguishing between battles on the open field and sieges, which I know were far more common and often less bloody, as everyone stood outside and waited for the people in the castle to starve and surrender.
In fact, I think I mentioned the very same fact in the Arena chat thread a few weeks back when someone mentioned medieval battles.
I suppose the reason why battles were uncommon was that it was incredibly rare for two sides to want to fight and destroy each other, because it would rely on a situation where for some reason both sides were confident of victory, which just didn't happen. The smaller side would just run away (manoeuvring) until more favourable conditions were met. Where-as guys in a castle didn't really have the option of running away from larger forces, so the people ensured of victory could set things in motion and engage combat.
I didn't know that about Anglo Saxon England, though as is common I'm only really aware in any detail of the battle of Stamford Bridge and the Battle of Hastings, which were both foreign invasions, so I doubt rules of etiquette would apply.
Pretty much ya, normally a field battle is hardly necessary almost regardless of goal. To take a few examples, if one side wishes to kill as many enemies as possible, why bother with a battle if they could go around torching cities, villages, and fields while avoiding their enemy's main army? If they want to take a city, why not lure the enemy into a wild goose chase elsewhere while the main army completes the siege or assault of said city?
If a confederation of desert tribes wishes to defend its homeland, why fight a battle at the frontiers if the enemy can be more efficiently defeated by denying them access to water supplies? If a civilized agrarian kingdom wants to turn back a rival kingdom's invasion, why not let that enemy get bogged down in besieging the frontier castles and towns while the King's agents gather a force large enough to scare any thoughts of continuing the invasion away from the enemy's mind? If a country at war needs to keep an enemy fleet at bay, why send the whole damned Grand Fleet steaming off to potential disaster if a commando raid can do the job just as well-not the least by sinking the enemy's own ships to block their own harbor. :K
I remember reading about a siege in the 100 years war that proves "civil war" is not an oxymoron. An English general was besieging a French castle. He managed to dig some kind of trench around the castle that was about to cause it to collapse or something, so rather than utterly crushing his enemies he properly warned the French general what he was doing. The French general didn't believe him, so the English bloke invited him outside to show him. The French dude was like, "Hmm... looks like you're right. OK, we surrender." Then the two armies had a pleasant banquet together.
That's one of gallantry that shows reality is stranger than fiction; at the battle of Fontenoy, an advancing English battalion halted a few dozen paces away from their French adversaries. The commanders of the French and the English battalions then bowed and invited each other's battalions to fire first before the fighting began in earnest--hence the quote from Lord Charles Hay, to which the Frenchman replied "Messieurs les Anglais, tirez les premier."
Funny enough, most of these examples involve the English now that I think about it...
