There's a britwank timeline on this forum. I view the start as starting on the edge realistic at best and the realism gets worse from there. A well written story though.
In it Britain pulls off Galipolli right. The Ottomans collapse and surrender. Romania Italy and Greece all join ww1 early on the allies side. The trade routes to Russia is open. Germanny pulls two armies out of France to attack Russia to prevent an Austrian collapse leaving France able to handle the western front with a small British Expeditionary Force.
