- Fight to capture, not kill. Also gives you the moral high ground.
- Never underestimate strength in numbers.
- Keep people who fight united and in one mind. Division or doubt amongst the ranks will lead to defeat. (Sow doubt in the Death Eaters? Make them afraid to fight, or make them fight each other?) Not a bad idea, Potter. The various followers of the Dark Lord rarely get along at the best of times. The competition to be his favorite is too strong. Finding a way to exploit this would be very helpful.
- Know when not to fight.
- Know your enemy and his strengths/weaknesses so you can plan better.
