Football League War Cup
From TheChels.info - The Chelsea Football Club WikiFA Cup. League football had been regionalised and teams fielded guest players, most who were servicemen on leave. The winners of the respective Football League North and South Cup competitions played each other for this trophy. Appearances and goals in the Football League War Cup or the Football League South do not count in players' official records.
Chelsea reached the Final in 1944-45, having won the Southern Final against Millwall at Wembley, but lost to Bolton Wanderers 2-1 at Stamford Bridge.
