Final answer:
The question appears to be confused with various historical events and figures like Garibaldi, Mussolini, and Richard Howe, without the accurate context or detail about Richard leaving Sicily with troops and gold.
Step-by-step explanation:
The student's question seems to be referencing a historical figure, Richard, leaving Sicily with a certain number of troops and an amount of gold. However, there seems to be a mix-up with different historical events and figures. The question might be referring to Garibaldi's invasion of Sicily in 1860 with a force of 1,000 red-shirted volunteers and no specific mention of gold. The provided reference material also mentions Mussolini's troops in the context of World War II, but not Richard, which suggests that this might be the incorrect context for the given question. Furthermore, the question might be confused with the British Admiral Richard Howe's arrival with over 100 ships but again, this is not the correct timeframe or context for the invasion of Sicily by Garibaldi. Thus, the answer to the specific question about Richard's troops and gold when leaving Sicily cannot be provided based on the provided references.
