Trust me, you won the BATTLE. You may not have won a war, but you scored a victory.
At the battle of Agincourt the English archers, vulnerable and horribly outnumbered by the superior french knights, were trapped with no where to go. You know who won? Those archers. Not only that, but they crippled France and began a new era where England wrested control of the French throne for a period. All because the trapped, unlikely archers stood up against a daunting foe.
Although you were trapped, you won a battle against what seemed like impossible odds. One battle won, that's all it took.
