The campaign at Gallipoli was meant to be a quick advance across the peninsula and north to Constantinople (Istanbul). Instead, owing such factors as the terrain and the valiant defence put up by the Turks, it bogged down into trench warfare. As the campaign grew from weeks to months, the trenches of both allies and Turks became more elaborate, and from early on in the campaign, maps were drawn of the developing trench systems.
