179th Tunnelling Company The 179th Tunnelling Company was one of the tunnelling companies of the Royal Engineers created by the British Army during World War I. The tunnelling units were occupied in offensive and defensive mining involving the placing and maintaining of mines under enemy lines, as well as other underground work such as the construction of deep dugouts for troop accommodation, the digging of subways, saps (a narrow trench dug to approach enemy trenches), cable trenches and underground chambers for signals and medical services. 179th Tunnelling Company is particularly known for its role at L'îlot de La Boisselle and for firing the Lochnagar mine during the Battle of the Somme 1916. The "Lochnagar" mine formed part of a series of 19 mines that were placed beneath the German lines on the British section of the Somme front to assist the start of the battle.
Vardar Offensive The Vardar Offensive (Bulgarian: Офанзива при Вардар ) was a World War I military operation, fought between 15 and 29 September 1918. The operation took place during the final stage of the Balkans Campaign. On September 15, a combined force of Serbian, French and Greek troops attacked the Bulgarian-held trenches in Dobro Pole ("Good Field"), at the time part of the Kingdom of Serbia (present day Republic of Macedonia). The assault and the preceding artillery preparation had devastating effects on Bulgarian morale, eventually leading to mass desertions.
