Chesspieces

I wish to leave your territor
yYet I enter your war situation
I don't have strong defences
And don't have an alternate route into which to retreat
I wish to escape from your trap
Yet I find myself trapped in another dilemma
I don't have the courage to determine victory or defeat
And don't have the good fortune of escape
I'm like a chesspiece
Attacking and retreating at your will
I am not the only knight in your eyes
Just an ordinary pawn
I'm like a chesspiece
Coming and going against my will
Raising of a hand without return; you never wavered
Yet I am under your control
