This module uses historical maps (vicinity and battle maps) from the Mexican American War as a way to study the war and many of its individual battles. It provides background information on the Battle of Monterrey, the Battle of Cerro Gordo, the Battle of El Molino del Rey, and the Battle of Chapultepec.

Using historical maps in the classroom

These maps can be combined with lessons on the Mexican American War as visual aids that drill down and show authentic battle plans, troop positions, and the resulting U.S.-Mexico border. They can also be combined with photographs of the cities or areas, text book readings, and Mexican American War documents, such as the Treaty of Guadalupe Hidalgo .

This module provides background information on the following significant battles and a list of links to related maps (in the links sidebar):

  • Battle of Monterrey
  • Battle of Cerro Gordo
  • Battle of El Molino del Rey
  • Battle of Chapultepec

Battle of monterrey (sept. 25, 1846)

Santa Anna had ordered General Pedro de Ampudia to retreat to Saltillo, yet, Ampudia disobeyed the order and went to the Mexican city of Monterrey, Nuevo León instead.

General Zachary Taylor positioned his troops north of Monterrey on Sept. 19 and captured the road leading to Saltillo on Sept. 20, effectively cutting General Ampudia’s troops off from reinforcements. The U.S. troops attacked the Mexican troops from two directions– General Taylor’s division attacked from the east, while General William Jenkins Worth’s division attacked from the west.

Monterrey battle plan

"Plan of MONTERREY, and Disposition of American Troops, just before the Attack, on the morning of Sept. 21, 1846"

The battle culminated with the bombardment of the city by U.S. howitzers (cannons) on Sept. 25. Monterrey was captured after a week of brutal battles. General Ampudia and General Taylor negotiated an 8-week armistice in exchange for the Mexican surrender of Monterrey. This armistice, in turn, earned General Taylor much criticism from President James K. Polk and the federal government, who did not think that the army had the power to negotiate such truces.

Battle of cerro gordo (april 17-18, 1847)

After U.S. forces captured the Mexican Port City of Veracruz, Veracruz, U.S. General Winifred Scott led his troops toward Mexico City. General Antonio López de Santa Anna’s Mexican troops blocked their route via the national road at the Cerro Gordo mountain pass (near Jalapa, Veracruz), between two large hills, La Atalaya and El Telégrafo. While Santa Anna had heavily defended this pass, he failed to station as many men on his left, an area he assumed to be impassible. Captain Robert E. Lee’s reconnaissance revealed this weakness and on April 18, General Scott commanded a flanking of the Mexican army. U.S. General David Twiggs led his men to the lightly defended area and General Gideon Pillow led his smaller troop toward the Mexican front.

The surprise attack forced Mexican troops to flee; and Santa Anna had to ride off without his wooden leg (which was then captured and kept by the U.S. army). After their victory, the U.S. army pushed forward to Puebla, Puebla in Mexico’s interior.

Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
is it a question of log

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
