If you are reading this, I have chosen you to take part in our little ambush. I thank you all for your selflessness in volunteering. I would like to reiterate that this mission will be very dangerous. I know you have become used to danger as a part of your daily lives. However, I feel it bears mentioning that on this particular mission, lives may be lost. I will, of course, completely understand if, and think no less of, anyone who wishes to retract their offer.
As I have stated, my good friend Mr Doge, as well as Mr Podmore, have volunteered to serve as bait of sorts. They will be discussing Elphias' upcoming move within the confines of the Ministry, which we know Lord Voldemort's spies have infiltrated. We expect Voldemort's followers to strike Thursday evening, when they believe Elphias will be moving, as his defenses will ostensibly not yet be erected. Of course, they will be in for quite the surprise!
In my previous correspondence I had mentioned two distinct groups for this job. The first group, with the more manifestly offensive task, will consist of Caradoc Dearborn, James Potter, Sirius Black, and Benjamin Fenwick. Dorcas Meadowes, Lily Evans, and Elphias himself will comprise the second, which is to set up the various wards and barriers.
I wish you the best of luck, of course, and shall be in further correspondence with you shortly with more details.
Yours, Albus P.W.B. Dumbledore
P.S. I seem to be missing a package of lemon drops, and I will be quite cross if anyone has taken them.
