Rhine River
During Julius Caesar's conquest of the Gaul he was stopped by the Rhine River. Caesar would later use his men to construct a bridge in very little time to cross the river. (Time toast won't allow the real date) -
Planks
The simplest beam bridge could be a log, a wood plank, or a stone slab laid across a stream. This is the type of materials they used, for there was no steel like we use today. (Time toast won't allow the real date) -
Pleasure Cruises
The plank was the basis of maritime transport: wood floats on water, and abundant forests meant wooden logs could be easily obtained and processed, making planks the primary material in ship building. Ship building then led to pleasure cruises being very popular for the wealthy. -
Beams
When Caesar constructed the Rhine Bridge, he used a a beam bridge. Double timber pilings were placed into the bottom of the river by winching up a large stone and releasing it, which would drive the supporting posts (or piling) into the riverbed. The most upstream and downstream pilings were slanted and supported by a beam, and multiple parts of these linked up to form the basis of the bridge. (Time toast won't allow the real date) -
Cruise Liners
With the emergence of pleasure cruises, many cruise liners competed against each other. Cruise liners were used for either transporting people, cargo, or both. The two rivals at the time were the Cunard Line and White Star Line. -
Unrestricted Submarine Warfare
Unrestricted submarine warfare is a type of naval warfare in which submarines sink vessels such as freighters and tankers without warning. This is a form of war called total war. This was included in Germany's U-Boat Campaign during WW1. -
U-Boat Campaign
The U-boat Campaign from 1914 to 1918 was the World War I naval campaign fought by German U-boats against the trade routes of the Allies. It took place largely in the seas around the British Isles and in the Mediterranean. In the course of events, German U-boats sank almost 5,000 ships with nearly 13 million gross register ton, losing 178 boats and about 5,000 men in combat. -
Sinking of Lusitania
The sinking of the Cunard ocean liner RMS Lusitania occurred during the First World War, as Germany used submarine warfare against the United Kingdom of Great Britain and Ireland. The Lusitania is one of the prime examples of the victims of the unrestricted submarine warfare/U-Boat Campaign, as it sank in 18 minutes. It greatly contributed to the American entry into the war. -
RMS Titanic
The Titanic was of the rival ocean liner, of the Lusitania, and naturally they were known as two of the most known ships at the time. They competed against each other up until they both sank, but the Titanic was a big example of a ship that is very similar to the Lusitania.
