The colonial volunteers of the 7th and 8th "Schützenkompanien" companies arrived by rail to stiffen the pressed Askari lines. The normally mounted 8th "Schützenkompanie" had left their horses at Neu Moshi. By late afternoon on 4 November, Lettow-Vorbeck ordered his last reserves, the 13th and 4th Askari "Feldkompanien" (field companies) – the 4th had just reached Tanga by train), to envelop the British flank and rear by launching bayonet attacks along the entire front to "bugle calls and piercing tribal war cries." At least three battalions of the "Imperial Service Brigade" would have been wiped out to a man, if they had not taken to their heels. All semblance of order vanished as Force B's retirement "degenerated into total rout."
