Gray Ranks
At first, Polish scouts from sabotage groups painted the whole phrase upon walls. However, it was soon abbreviated to the letters PW, which over time came to symbolise the phrase "Polska Walcząca" ("Fighting Poland"). Early in 1942, the AK organised a contest to design an emblem to represent the resistance movement, and the winning design "(pictured)" by Anna Smoleńska, a member of the Gray Ranks who herself participated in minor sabotage operations, combined the letters P and W into the Kotwica.
