After 1914, sporadic attempts were made at seasonal truces; a German unit attempted to leave their trenches under a flag of truce on Easter Sunday 1915 but were warned off by the British opposite them. In November, a Saxon unit briefly fraternised with a Liverpool battalion. In December 1915, there were orders by the Allied commanders to forestall any repeat of the previous Christmas truce. Units were encouraged to mount raids and harass the opposing line, whilst communicating with the enemy was discouraged by artillery barrages along the front line throughout the day; a small number of brief truces occurred despite the prohibition.
