Volume 20: All Out War - Part One is the twentieth volume of Image Comics' The Walking Dead that includes issues 115-120, all of which were released biweekly. In this volume, Rick leads his newly formed "army" with the Hilltop and the Kingdom in an attack against the Sanctuary. Things go smoothly at first as Rick's forces manage to trap Negan inside the Sanctuary, but as they attack Negan's outposts many of Rick's closest friends begin dying and they wonder if their initial victory was just luck. Eventually, Negan mounts a counter attack on Alexandria and things go from bad to worse.
