The strategy used by both are similar.
Before invading the country Napoleon used to send a messenger to send to the king waiting outside the outskirts of the invading country, similarly the modern napoleon writes a resignation letter filling it with poisonous fumes.
Dear Jhandu Balm (read: Boss)It's extremely hard for me to do what I must do today. My experience with you and this company has been so fulfilling and joyful that I almost cried when I realized I had to move on to a different career opportunity.This letter is to officially notify you of my resignation from the company. My last day will be today.I hate to leave. You have been such a mentor to me. Your guidance and friendship have made me regard you as another parent, of which I love so much. Hopefully we can still stay in touch. Maybe even get together for a beer this summer.Again, my dear friend, thanks so much for allowing me to know such a well-adjusted and intelligent person such as yourself.Let's get together for lunch soon,
