By 1910 this plan had changed: none of the 1st Lancashire transferred to the fortress company, but the telegraph company had been expanded to form the Western Wireless Telegraph, Cable Telegraph and Air-Line Telegraph companies, collectively known as the Western Signal Companies [REF].
The Commanding Officer of the companies from 1912 was Lt-Col F.A.Cortez-Leigh, transferred from a TF battalion of the Lancashire Fusiliers.
