The War Office urged Marshall to send a brigade to Dunsterville but he claimed that mounted in Fords and a force of armoured cars, would be sufficient to get beyond Kermanshah. The force could to the Caspian Sea by June and then the waters could be controlled by arming ships; if he was wrong, reinforcements could be sent later. During the discussions, the Bolsheviks in Caucasus requested that Bicherakov attack the Jangalis to protect Baku, to which he agreed, in return for their acquiescence in British involvement. Dunsterville wanted to depart on 30 May but was delayed by the War Office until 1 June and allowed to move on, provided that the road was adequately guarded. Ottoman forces were west of the road at Tabriz and the Jangalis held the road at Manjil. Just after the fourth party of Dunsterforce had arrived, Dunsterville sent parties of his Officers and NCOs with pack-wireless stations, to Zenjan and Bijar, about north-west of Kazvin and Hamadan. Their objective was to recruit local Kurds, to bar the two tracks through Kurdistan against an Ottoman advance. Sehneh, on a southern track from Urmia to Kermanshah, was left until July, when Marshall sent troops to occupy the town.
