The Great War: Week by Week 100 Years Later S02E40 - Week 62: The Battle of Loos - New Offensives on the Western Front

After weeks of preparation the French and British Armies unleash a new offensive on the Western Front. Not only is it supposed to relieve pressure on the Russians on the Eastern Front but the Entente wants to achieve the decisive breakthrough. The French actually break through German trenches only to realise that they have a second line of trenches completely in tact right behind the first line. The British attack at Loos also turns into carnage even though the British use gas for the first time.
