The Art of Tetman Callis

“Nine-tenths of tactics were certain enough to be teachable in schools; but the irrational tenth was like the kingfisher flashing across the pool, and in it lay the test of generals. It could be ensued only by instinct (sharpened by thought practising the stroke) until at the crisis it came naturally, a reflex.” – T. E. Lawrence, Seven Pillars of Wisdom
