In November 1936, Jacobsen had been able to persuade the Labour movement to provide some funding, over the objections of some in the Scottish Labour Party. In January 1937 a second convoy, again led by Jacobsen, travelled to Spain. The second SAU expedition focused their efforts in the capital, which was suffering from the bombardment of the Siege of Madrid. Their work was enthusiastically praised in "Politica", a newspaper in Madrid. After months working to evacuate the wounded and provide relief, under pressure from bombings, the second convoy returned in July, to be replaced by a third convoy in September.
