Prior to its arrival, the Advance Guard lured the Dursley family away from their house. Nymphadora Tonks fabricated a letter informing them that they were among the finalists for the All-England Best-Kept Lawn competition, and the family was heading to the awards ceremony when the Advance Guard arrived at 4 Privet Drive. Out of the group, Harry only knew Lupin from before, and had spoken to the real Alastor Moody and Dedalus Diggle only briefly. This was Harry's first meeting with the remaining members, most notably Nymphadora Tonks and Kingsley Shacklebolt.
