Security Measures
Ships and sailors in port for industry-related operations faced new restrictions from the government and heightened scrutiny from the Coast Guard. Everyone who worked at the docks had to be able to show identification and a license to work there. All ships had to acquire permission from the Coast Guard to enter and leave the port.2
Prior to the war, more than 90% of the town's oil-related traffic moved by water in tankers and barges. During the war years, much of the transport of goods shifted to land due to wartime restrictions and danger in shipping lanes.3
During the early years of the war, ships traveling alone off the Florida, Atlantic and Gulf coasts were at risk from German U-boats. Although the presence of German U-boats in the Gulf was kept secret from American civilians, shipping patterns and procedures were greatly affected. At first, Navy commanders were unwilling to assign Navy ships for convoy protection due to war needs in the Atlantic and Pacific theaters. Instead they sent destroyers and Coast Guard vessels to hunt U-boats in heavily-traveled sea lanes. This proved ineffective and U-boats continued to sink a large number of cargo vessels. Finally, in April of 1942 Admiral Adolphus "Dolly" Andrews, commander of the Eastern Sea Frontier of the United States, took over command and began phasing in armed convoys of all shipments. Ships from Houston and Texas City would sail to Galveston, where convoys were formed and escorted.4
Stationed in Corpus Christi
While stationed in Corpus Christi, Duane Barger watched for submarines.
Duane Barger: Now they had submarines in the Gulf. And when I was stationed in Corpus Christi, that's one of the things on our training that we were supposed to be looking for: submarines. We flew all over the Gulf, and out in the Atlantic for a little ways. We didn't go far out in the Atlantic. But off of Florida and out there. You was always looking. Because you could see a submarine in like the Gulf, you could see a submarine. Looks like a big fish down there, until you're up high.
