435 in overwhelming white East Baltimore, both Thurgood Marshall and the national secretary of the NNC, John P. Davis spoke. As was the case in the early 1930s, however, organizing steel in the Baltimore region toward the end of the decade was tough going. According to historian and journalist Mark Reutter, after six months only about 3,000 of the 15,500 workers at Sparrows Point had joined SWOC - a big increase over the 400 or so members the Amalgamated claimed a year previously, but not enough to put steel on the cutting edge of the CIO in the region. Nationally SWOCs carefully planned and administered leadership of the CIO effort was preempted by the popular upsurge in auto that resulted in the wave of sit-down strikes centered in Flint, Michigan, and that established the United Auto Workers as one of the CIO's most energetic unions. By the end of 1936, SWOC efforts in Baltimore were also overshadowed, not in this case by auto workers, but by another sector of the local working class with a powerful local tradition of struggle. On November 1, 1936, the seamen in the port of Baltimore went on strike. The seamen's strike of 1936-37 - the 100-Day Strike that I. Duke Avnet referred to in his testimony above — was not, formally speaking, a CIO effort. Rather it was the work of insurgent forces in the AFL International Seamen's Union (ISU) that were convergent with the CIO. The strike, which rapidly encompassed all the major Atlantic and Gulf ports, was called with three interlocking objectives.

Thirdly, it was a strike agaiitet the shipping companies for a decent contract. Underlying these three
